Answer:
{(0, -4), (1, -2), (2, 0), (3, 2), (4, 4)}
<u>Input values (x)</u> = {0, 1, 2, 3, 4}
<u>Output values (y)</u> = {-4, -2, 0, 2, 4}
Step-by-step explanation:
Given the linear equation, y = 2x - 4, you could practically choose any input value (for x), to have an output value (for y).
If x = 0:
y = 2(0) - 4
y = 0 - 4
y = -4
First ordered pair: y-intercept = (0, -4)
If x = 1:
y = 2(1) - 4
y= 2 - 4
y = -2
Second ordered pair: (1, -2).
If x = 2:
y = 2(2) - 4
y= 4 - 4
y = 0
Third ordered pair: x-intercept = (2, 0).
If x = 3:
y = 2(3) - 4
y = 6 - 4
y = 2
Fourth ordered pair: (3, 2).
If x = 4:
y = 2(4) - 4
y = 8 - 4
y = 4
Fifth ordered pair: (4, 4).
Your input values (x) = {0, 1, 2, 3, 4}
Your output values (y) = {-4, -2, 0, 2, 4}
