Step 1: Calculate the slope of the given line equation

NOTE: Putting the equation in the form y = mx (+c) and attempting to

extract  the m

Step 2: Find the slope of the another line

NOTE: i) Parallel lines have the same slope.

ii) Perpendicular lines have slopes that are opposite reciprocals, like

\frac{a}{b} \text{ and } \frac{-b}{a} The slopes also have

a product of -1.

Step 3: Use the slope of line and a point on line to find its y-intercept.

EXAMPLE: Plug the slope m = -2 and the point (-6, 4) into the

slope-  intercept formula. Then solve for the y-intercept b.

y = mx + b

4 = -2(-6) + b

Step 4: Use the slope of line and the y-intercept of line to find the equation of the line.

EXAMPLE: Plug the slope m = -2 and the y-intercept b = -8 into the

slope- intercept  formula.

y = mx + b

y = -2x + -8
