What value of a in the equation ax - 4 = 2y would give a line with a slope of 2?

a=4

Step-by-step explanation:

ax - 4 = 2y

We need to get the equation is slope intercept form y = mx+b.

Lets solve for y

Divide each side by 2

a/2 x - 4/2 = 2y/2

a/2 x - 2 = y

or y=a/2 x - 2

The slope is a/2 and the y intercept is - 2

We want a slope of 2 so a/2 = 2

a/2=2

Multiply each side by 2

a/2 * 2 = 2*2

a = 4
