Question

Identify the x-intercept and y-intercept of the line 2x -5y =20

Answer 1

To find the x intercept, sub in 0 for y and solve for x
2x - 5y = 20
2x - 5(0) = 20
2x = 20
x = 20/2
x = 10....x intercept is (10,0)

to find the y intercept, sub in 0 for x and solve for y
2x - 5y = 20
2(0) - 5y = 20
-5y = 20
y = -20/5
y = -4....y intercept is (0,-4)

Answer 2

1. Slope 0.800/2.000 = 0.400

2. x-intercept = 20/2 = 10

3. y-intercept = 20/-5 = 4/-1 = -4.00000

Hope this helps. :)
