Question 589338
To find the x-intercept, let y = 0 and solve for x.

-5x + -8(0) = -40

-5x + 0 = -40

-5x = -40

x = -40/-5

x = 8

The graph of this equation crosses the x-axis at the point (8,0).


To find the y-intercept, let x = 0 and solve for y.


-5(0) + -8y = -40

0 -8y = -40


-8y = -40

y = -40/-8


y = 5


The graph of this equation crosses the y-axis at the point (0,5).

The x-intercept is x = 8, which is also written as (8,0).

The y-intercept is y = 5, which is also written as (0,5).
