Slope-Intercept Form
Writing the Equation
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
