Answer:

x = -5/4

y = 1

Explanation:

4x - 5y = -5

To find the x-intercept/zero, substitute y = 0

4x -5 x 0 = -5

4x -5 x 0 = -5

Any expression multiplied by 0 equals 0

4x - 0 = -5

Removing 0 doesn't change the value, so remove it from the expression

4x = -5

4x = -5

Divide both sides of the equation by 4

x = -5/4

4x - 5y = -5

To find the y-intercept, substitute x = 0

4 x 0 - 5y = -5

Solve the equation for y

y = 1
