Answer:
A
Step-by-step explanation:
The equation can be rearranged to slope intercept form of
y = 4x - 2
We know that the y-intercept is -2 because it is the leftover part, and the slope is 4 because it is 4x.
You can plug in an x-value from the table into the equation, and if it is correct, all the values should end up with the same and correct y-value.
-5 times 4 is -20
-20 -2 = -22.
Correct so far
0 times 4 is 0.
0 - 2 = -2.
Correct so far.
3 times 4 is 12.
12 - 2 = 10.
Correct!
Checking B:
-22 times 4 = -88.
-88 - 2 = -90.
Wrong.
Checking C:
-5 times 4 = -20.
-20 - 2 = -22.
It must be A
B
because proportion is right vertical
if additive inverse then
(1/3y)+7
if multiplicative inverse then
3y-7
if both then
3y+7
if in this way
f(x)=(1/3x)-7
f(-x)=(-1/3)-7
