Question
Find the y-intercept of the line by substituting 0 in for x and solving for y.3x -2y = -18
Solution
To find the y-intercept of the line, we substitute x = 0 into the equation and solve for y.
The equation is 3x - 2y = -18.
Substituting x = 0, we get:
3(0) - 2y = -18 -2y = -18
To solve for y, we divide both sides of the equation by -2:
y = -18 / -2 y = 9
So, the y-intercept of the line is 9.
