Find the equation of each line described below. .

A line with slope of

that passes through the point . A line with a slope of

is horizontal, so all points have the same -coordinate.Substitute

for in the equation below. Then substitute the-coordinate from the given point in for.A line that passes through the points

and . What is the rise from the first point to the second? What is the run? Divide the rise by the run and you will have the slope.

Substitute the slope for

in the equation below. Then substitute the- and- coordinates of one of the given points forand, respectively. Then solve for.
