Find the slope of the line that passes through ( 5, -4) and (9, -4 ). Step 1: Label the points:
First point: (
x1 , y1) =
Second point: ( x2 , y2) =

Step 2: Write the formula: and Substitute the numbers:
Slope m = y2 - y1x2 - x1
Step 3: Simplify:

Slope m =

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
