find the y - intercept of the line 15x + 18y = - 20. write your answer as an integer or as a simplified proper or improper fraction, not as an ordered pair.
Answer
Explanation:
Step1: Recall y - intercept formula
The y - intercept occurs when (x = 0). So we substitute (x=0) into the equation (15x + 18y=-20).
Step2: Solve for y
When (x = 0), the equation becomes (18y=-20). Then (y=\frac{-20}{18}=-\frac{10}{9}).
Answer:
((0,-\frac{10}{9}))
