Point-Slope Form

Line through a point with a given slope.

Formula

y−y1=m(x−x1)y - y_1 = m(x - x_1)

Variables

mSlope
x_1,y_1A point

Example

Line through (2, 3) with slope 4: y − 3 = 4(x − 2), i.e. y = 4x − 5.

Did You Know?

Point-slope form is the fastest way to write a line's equation when you know one point and the slope.
