x-intercept = -1, y-intercept = -4

Explanation:

Intercept form of linear equation is x/a + y/b = 1

Given y = -4 -4x

4x + y = -4

x/-1 + y / -4 = 1 is the intercept form equation.

x-intercept = -1, y-intercept = -4

"x-intercept "=-1," y-intercept "=-4

Explanation:

"to find the intercepts, that is where the graph crosses"
"the x and y axes"

• " let x = 0, in the equation for y-intercept"

• " let y = 0, in the equation for x-intercept"
