The point slope formula is: y -y1 = m(x - x1)
To use the point slope formula, substitute the slope for m, and the coordinates of the point for x1 and y1
y - y1 = m(x - x1) Point-slope formula
y - (-4) = 5(x - (-6)) Substitution
y + 4 = 5(x + 6) Subtracting negatives means adding positives
y + 4 = 5x + 30 Distribute the 5
y + 4 - 4 = 5x + 30 - 4 Subtract 4 from each side
y = 5x + 26 Simplify
