Question

Desperately need help, i can not grasp how to do this!

Find the X intercept Y intercept and slope for the following equation . 18x-y=-54

Answer 1

The slope is 18 and the y intercept is 54.

x intercept is -3

Explanation:

Let's change it to pt slope form, y=mx + b where m is the slope and b is the y intercept.

18x - y = -54

-y = -54 - 18x

y = 54 + 18x

The slope is 18 and the y intercept is 54.

To get the x intercept, set y = 0 and solve.

0 = 54 + 18x

-54 = 18x

-54/18 = x

x = -3
