If AB and BC are equal then AC should be 29

How did I get this?
x+4=2x-10
14=x

Plug it in
AC= 2(14)+1
AC=28+1
AC=29

KEEP IN MIND THIS WILL MOSTLY LIKELY ONLY WORK IF IT SAYS AB AND BC ARE EQUAL

What is a line that passes through (-7,3 and (-6,-1)
Serggg [28]

Answer:

y=-4x-25

Step-by-step explanation:

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

m=(-1-3)/(-6-(-7))

m=-4/(-6+7)

m=-4/1

m=-4

y-y1=m(x-x1)

y-3=-4(x-(-7))

y-3=-4(x+7)

y=-4x-28+3

y=-4x-25
