Given the equation:

2x + 3y = -18 

Find the x and y-intercepts.

Solution:

We can find the x and y-intercepts individually.

x-intercept:
To find for x-intercept, we simply equate the value of y to 0, then solve for x.

2x + 3(0) = -18

2x = -18

Divide both sides by 2 in order to determine the value of x.

2x/2 = -18/2

x-intercept = -9

To find for the y-intercept, we equate the value of x to 0 then solve for y.

2(0) + 3y = -18

3y/3 = -18

y-intercept = -6

Final answer:

x-intercept = -9
y-intercept = -6
