If you are given 2 points on the line, you can calculate slope using
the slope formula
If 2 lines are perpendicular, then
the slopes are opposite and reciprocals
The slope of the line that passes through the points (5, 1) and (5, -7) is
undefined
The slope of the line x=-5 is
undefined
The slope of a horizontal line is
zero
The slope of the line 2x + 3y =6 is
-2/3
The slope of the line that passes through the points (3, -2) and (-2, 5) is
-7/5
In the equation y = mx +b, the slope is represented by
m
Compare the lines y=1/5x + 3 and y = -1/5x. Are these lines parallel, perpendicular or neither?

If 2 lines are parallel, then
the lines have the same slope
