Choose the correct set of y-values for the function y = -2x when x = -2, 0, 2. (-2, -4), (0, 0), (2, -4) (-2, 4), (0, -2), (2, 4

Answer:
x = -2
(-2 , 4)
x = 0
(0 , 0)
x = 2
(2 , -4)
Step-by-step explanation:
y = -2x
we have to discover the value of y for when x is worth (-2, 0, 2)
so let's replace the x with each one and write your ordered pair
1) x = -2
y = -2x
y = -2(-2)
y = 4
( x , y)
(-2 , 4)
2) x = 0
y = -2x
y = -2(0)
y = 0
( x , y)
(0 , 0)
3) x = 2
y = -2x
y = -2(2)
y = -4
( x , y)
(2 , -4)
so we have that for each value of x we have a different ordered pair
Since both sides has same factor (x+6), we can set (x+6) equal to 0.
So we would have one of solution x = -6. (because this would have us x·0 = 4·0 )
Now when x is NOT equal to -6, we can divide both sides by (x+6), leaving us
x = 4
So answer is x = -6 or 4.
The slope of a line is given by the ratio of the rise to the run of the line.
The value of, y is <u>4</u>
Reasons:
The given points on the line are; (-4, y), and (5, 7)
The slope of the line, = 
Required:
To find the value of <em>y</em>
<em />
Solution:
The formula for the slope is given as follows;
Where;
(x₁, y₁) = (-4, y)
(x₂, y₂) = (5, 7)
Which gives;
3·(7 - y) = 1·(5 + 4) = 9
21 - 3·y = 9
3·y = 21 - 9 = 12
The value of, y = <u>4</u>
