Answer: The y-intercept is -12
The x-intercept is 8
Step-by-step explanation: Factor out 3
Divide all by 3 to simplify.
9x - 6y = 72 is equivalent to
3x - 2y = 24
At this point, you can substitute 0 for x and solve for y
3(0) -2y = 24. -2y/-2 = 24/-2
y = -12
And substitute 0 for y and solve for x.
3x -2(0) = 24. 3x/3 = 24/3
x = 8
OR Change to slope intercept form:
y = mx + b. b is the y intercept.
-2y = -3x + 24. Solve for y.
Divide all by-2
y = 3x/2 - 12.
The y-intercept is -12
To find the x-intercept, substitute 0 for y and solve for x.
0 = 3x/2 -12 Add 12 to both sides.
12 = 3x/2. Multiply both sides by 2/3
8 = x
The x-intercept is 8
