4. The value of the x-intercept for the graph 4x - 5y = 40 is:

x = 10

Step-by-step explanation:

To find the x - intercept let y = 0 in the equation and solve for x

Given

4x - 5y = 40, then

4x - 5 (0) = 40, that is

4x = 40 (divide both sides by 4)

x = 10

Thus the y - intercept = 10 ⇒ (10, 0) ← coordinates of y - intercept
