Point-Slope Form
Introduction
Example 1
Find the equation of the line that has slope m = 4 and passes through
the point (-1, -6).
Step 1. Identify the slope and point
m = 4, x1 = -1, and y1 = -6.
Step 2. Substitute the values in the Point-Slope Formula and simplify.
y - y1 = m(x - x1)
y - (-6) = (4)(x - (-1))
y + 6 = 4(x + 1)
