Answer:
the y- intercept is (0, - 12 )
Explanation:
x² - x - 12 = y
the y- intercept is the point on the y- axis where the graph crosses.
the x- coordinate of any point on the y- axis is 0
substitute x = 0 into the equation and solve for y
0² - 0 - 12 = y
0 - 0 - 12 = y
- 12 = y
the y- intercept of the equation is (0, - 12 )
