Question

Complete the point-slope equation of the line through (-8,-8)(−7,9)

Use exact numbers
y-9=_______

Answer 1

y-9 = 17(x+7)

Explanation:

Points given (-8, -8) and (-7, 9)

Point-slope is the general form y-y₁=m(x-x₁)

Finding the value of m using the given points:

• m= (9 - (-8))/(-7 - (-8)
• m = 17/1= 17

Completing the given equation using point 2:

• y - y₁ = m (x - x₁)
• y - 9 = 17(x - (-7))
• y - 9 = 17(x+7)
