SLOPE FORMULA
Slope is defined as .
To find the slope of a line containing the points (x 1 , y 1 ) and (x 2 , y 2 ),
.
What does has no intersection with mean? It means that the lines are parallel,
which in turn means that the lines have the same slope. If you know the slope-
Which of the following lines has no point of intersection with the line y
= 4x + 5?
