Question

A line has a slope of 8 and includes the points (-7,10) and (-9,h). what is the value of h

Answer 1

I would say -6 because (-9 - -7 = -2, so 8 x -2 = -16, so subtract 16 from 10 to get -6)

Answer 2

• - 6

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

Use the slope equation:

• m = (y₂ - y₁) / (x₂ - x₁), where m- slope

Substitute given values for the slope and coordinates and and solve for h:

• 8 = (h - 10) / (- 9 - (- 7))
• 8 = (h - 10) / (- 2)
• -16 = h - 10
• h = -16 + 10
• h = - 6

The value of h is - 6.
