I believe that it's 6.

Set y = 0 -x = 8 so that x = -8 is the x-intercept. Set x = 0 2y = 8 so that y = 4 is the y-intercept.
x is the same, so 8 y is undefined
-6
The graph of [ x=8 ] is a vertical line through the point 8 on the x-axis. It never touches the y-axis, and has no y-intercept.

X intercept = -4 Y intercept = 2
y = -x + 8
Add 8 to the x value, so f.e. If x=4, the y intercept = 4+8 =12 No, the y intercept is the value of y when the value of x = 0, so the y intercept of the equation is 8. In the general form y = mx + b, b will always be the y intercept.
x-intercept:2x = 24x = 12y-intercept:-3y = 24y = -8
(4,0)
-4x + y = 8At the x-intercept, 'y' is zero.-4x = 8-x = 2x = -2At the y-intercept, 'x' is zero.y = 8
