Find the x and y-intercepts of each equation and then graph the line x +2y=8?

The x intercept is the value of x when y=0.

x + 2y = 8
x + 0 = 8
x = 8

The y intercept is the value of y when x=0.

x + 2y = 8
0 + 2y = 8
y = 4

To draw a graph, find any two points and draw a line through them. Since you already found the intercepts, use those.
