Find the equation of the line pictured

To find the slope of a line given two points, use this formula:

Given the points (-1, 3) and (2, 5), the difference in the y-values is ​ (a)   and the difference in the x-values is ​ (b)   , so the slope is ​ (c)   ​

• 2
• 3
• 2/3
• 1
• 4
• 1/4
• 3/2

The slope of the line that contains the points (-3, 3) and (-1, -2) is:
