Question

The pair of points (-4, y) and (5, 7) lie on a line with slope 1/3 What is the value of y? You must show all of your work to receive credit please help me

Answer 1

• 4

-----------------

Use slope formula and solve for y:

• 1/3 = (7 - y) / (5 + 4)
• 1/3 = (7 - y) / 9
• 9/3 = 7 - y
• 3 = 7 - y
• y = 7 - 3
• y = 4

The value of y is 4.
