Answer:
20
Step-by-step explanation:
<span>Hello : let
A(5,-4) B(-1,8)
the slope is : (YB - YA)/(XB -XA)
(8+4)/(-1-5) =-2
an equation is : y=ax+b a is a slope</span>
y = -2x +b
the line through point A(5,-4) :
-4= -2(5)+b<span>
<span>b = 6
the equation is : y =-2x+6</span></span>
6.4/8 = y/6 = x/7
0.8/1 = 4.8/6 = 5.6/7
6.4/8 = 4.8/6 = 5.6/7
x = 5.6 ; y = 4.8
I think that’s how you do it but not 100% sure
What r the options so i can get an idea
