(0,-4) fits the linear equation perfectly.

Hope this helps.

Answer:

the y-intercept is the point (0, -4) on the plane

Explanation:

In order to find the y-intercept, write the equation in "slope intercept form" solving for "y":


2\,y=x-8\\y=(x-8)/(2) \\y=(x)/(2) -(8)/(2) \\y=(x)/(2) -4

Recall now that the y-intercept is the value at which the line crosses the y-axis (when x = 0), therefore:


y=(x)/(2) -4\\y=(0)/(2) -4\\y=-4

So the y-intercept is the point (0, -4) on the plane.
