Question

Which graph represents the function y = 2x – 4?

Answer 1

Answer:

A coordinate plane with a line passing through (0, negative 4) and (2, 0).

Step-by-step explanation:

rewrite the equation in standard form (Ax+By=C). the equation in standard form is 2x-y=4. to find the intercepts, let one of the values equal 0.

y intercept (let x equal 0)

2x-y=4

2(0)-y=4

-y=4

divide both sides by -1

y=-4

the y intercept is (0,-4)

x intercept (let y equal 0)

2x-y=4

2x-0=4

2x=4

divide both sides by 2

x=2

the x intercept is (2,0)
