Question

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

A. -4/5
B. 4/5
C. -8
D. 10

Answer 1

c. -8

Explanation:

Slope = 1.600/2.000 = 0.800

x-intercept = 40/4 = 10

y-intercept = 40/-5 = 8/-1 = -8.00000

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

4*x-5*y-(40)=0
