Slope-Intercept Form

To write an equation when given the slope and y-intercept, replace m with the given slope and b with the given y-intercept in the equation y = mx + b.

Example Write an equation in Slope-Intercept form given y-intercept of (0,5) and slope = 2.

(0,5) is the y-intercept, therefore b = 5

Slope = 2, therefore m = 2

y = mx + b

y = 2x + 5
