Question

PLEASE HELP: Complete the equation of a line through (-10, -7) and (-5, -9).

Answer 1

find slope m

m=y2-y1/x2-x1

m=-9-(-7)/-5-(-10)

m=-9+7/-5+10

m=-2/5

y=-2/5 x+b ( find b at point (-10,-7)

-7=-2/5(-10)+b

-7=20/5+b

b=-7-4

b=-11

y=-2/5 x -11 slope intercept form

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

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