1. Tell whether the line containing (-1,-2) and (4,4) and the line containing
(6,3) and (-1, -3) are parallel.

Step-by-step explanation:

Two lines are parallel if they have the same slope.

To find the slope of the line that passes through two points, and , you can use the following formula:

For the first set of points, and , we can find the slope with the following:

For the second set of points, and , we can find the slope with the following:

Since the two slopes are and , the two lines are not parallel.
