How do you find the y-intercept when you know the slope and at least ONE point on the line?

• you use the quadratic formula

• you use slope-intercept for equation and plug in the y-coordinate, x-coordinate, and the slope and then solve for b.

• you use standard form equation and plug in a, b, and c.

• you cannot find the equation of a line with that information
