the answer is y=8 and x=4

Explanation:

see this graph:https://www.desmos.com/calculator/r4vhmjhwyy
you already know that the y-int would be 8 from the graph b/c remember the formula y=mx+b and the b would always be your y-int and then you just have to graph to find what the x is

The y-intercept is (0,8).
The x-intercept is (4,0).

Explanation:

To find the y-intercept, plug in 0 for x and you solve to get 8

y=-2x+8

y=-2(0)+8

y=0+8

y=0

To find the x-intercept, plug in 0 for y and you solve to get 4

y=-2x+8

0=-2x+8

2x=8

x=0

The y-intercept is (0,8)
The x-intercept is (4,0)

Explanation:

y-intercept: you make x=0 so y= 0+8 so y intercept is(0,8)
x-intercept: you make y=0 so 0=-2x+8=> -2x=-8 so x-intercept is (4,0)
