Which of the following equations represents the line that passes through the points (-5, 10) and (2, 8)? Select one: A. y=−2x/7+

Brut [27]

Answer:

y=-2/7x+60/7

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-10)/(2-(-5))

m=-2/(2+5)

m=-2/7

y-y1=m(x-x1)

y-10=-2/7(x-(-5))

y-10=-2/7(x+5)

y=-2/7x-10/7+10

y=-2/7x-10/7+70/7

y=-2/7x+60/7
