Problem: what is the y intercept of the line whose slope is 3 passing points (1,-2)

i need help finding the y intercept of the line whose slope is 3 passing through points (1,-2)

The general equation is y = mx + b.

Re-work that equation to find b.

b = y - mx

b = -2 - 3(1)

b = -2 - 3

b = -5

**Answer: the y-intercept is -5.**
