(-2,13) and (0,5)
Applying the above formula will get you ((13-5)/(-2-0)) = 8/-2= -4
-4 is the slope
The y-intercept is the y-value where the line crosses the y axis. In this function, the y-intercept is 5.
The slope intercept form can be written in the form: y = mx + b where m is the slope and b is the y-intercept. Therefore, substitution of the values we’ve got will give us the following answer:
y = -4x + 5

Answers
Explanation: 1/35 divided by 1/7= 1/5. 1/7 of/x 1/5= 1/35.
The value of unknown number would be equal to 1/5
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the unknown number.
A negative divided by a negative is positive, then;
1/7 of x is 1/35
1/35 divided by 1/7
1/7 of x 1/5 = 1/35.
x = 1/5
Therefore, The value is x = 1/5

Point U on a graph is located at (4,8), Point V on the same graph is located at (12, 14).
Which point lies on Line UV?
A. ( 7 , 12 )
B. ( 10 , 14 )
C. ( 16 , 22 )
D. ( 20 , 20 )
Answers
Answer:
D
Step-by-step explanation:
gradient is change in y/change in x
gradient of UV = 14-8/12+4=3/4
use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept
use one of the coordinates of U or V, I'll use (4,8)
[tex]y = mx + c[/tex]
[tex]8 = \frac{3}{4} (4) + c[/tex]
[tex] 8 = 3 + c[/tex]
c is 5
the equation for UV is
[tex]y = \frac{3}{4} x + 5[/tex]
insert each X coordinate given in the question to see if it gives the same y coordinate
when x is 20, y is also 20 so the answer is D

Step-by-step explanation:
Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?
You need to turn 15% into a decimal.
Move the decimal point to the left 2 spaces.
15 ---> 1.5 ---> 0.15
Now multiply 0.15 by $1,580.
0.15 × $1,580
Which is $237.
Now subtract $1580 - $237.
Which is $1343.
Answer:
$1580*15/100=$237that is discount rate.
$1580-237=$1343 actually pay

Function 2: (image below)
Which statements are true?
Select each correct answer.
Function 1 has a greater rate of change than function 2.
Function 2 has a greater rate of change than function 1.
Function 1 has a greater y-intercept than function 2.
Function 2 has a greater y-intercept than function 1.
Answers
Answer:
Function 1 has a greater Y intercept than that of function 2
Step-by-step explanation:
Y intercept can be found by replacing x by 0 or
x = 0 0f the given function.
in this case Function 1 has a Y intercept of 5 when x =0
on the other hand, function 2 crosses the y axis once at -1 which is the y intercept.
you can now clearly see that
y = 5 > y = -1
---> 5>-1
so that's why we conclude that 1 has a greater Y intercept.
Question about finding intercepts from a table. Hope someone can answer!
Answers
Now if you are familiar with the equation of a line in slope intercept form, it will look like this: y=mx+b. Here the ‘m’ is the slope and the ‘b’ is your y-intercept. What you need to do is use any two points given from the table and find the slope. To do that follow the steps below:
1. Pick two points. Let’s take the first two.
(-28, -54) And (-21, -40)
2. Subtract the two y values, -40 - (-54) = 14
3. Subtract the two x values, -21 - (-28) = 7
4. Now take your answer from step 2 and divide it by your answer in step 3. This will be 14/7, which will be 2.
Your answer from step 4 is your slope, or ‘m’.
(That series of steps was basically change in y over change in x, you can look that up if you are still confused)
Now that you know m, your incomplete equation will be this:
y=2x+b.
Next you will pick any point from the table again, and replace it with x and y in the equation. Let’s pick the second point, (-21,-40)
Plug this in: -40 = 2(-21) + b
Solve for b and you will get your answer.
-40 = -42 + b
b=2
Your answer is 2, that is the y intercept.
(The full equation of the line from that table would be y=2x+2)

3/4c-7/12+7/24c+2/3-1/6c
simplify the expression
Answers
Explanation: separate the c terms and the non-c terms. 3/4c + 7/24c - 1/6c = 7/8c
-7/12 + 2/3= 1/12
therefore, it’s 7/8c + 1/12
The simplification of the given expression (3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c is (21/12)c + 1/12.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given expression,
(3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c
Combined likely terms,
⇒ (3/4)c + (7/24)c - (1/6)c - 7/12 + 2/3
⇒ (3/4 + 7/24 - 1/6)c + 2/3 - 7/12
⇒ [(18 + 28 - 4)/24]c+ (8 - 7)/12
⇒ (42/24)c + 1/12
⇒ (21/12)c + 1/12
Hence "The simplification of the given is (21/12)c + 1/12".
