Answer:
Step-by-step explanation:
Hello : let A(2,11) B(8,14)
the slope is : m = (YB - YA)/(XB -XA)
(14-11)/(8-2) = 3/6 = 1/2
the slope is m=1/2 so : y=1/2 x +b
passes through A(2,11) B(8,14)
for exempl A(2,11) ; when x=2 y =11
1/2(2)+b = 11
b = 10
an equation in the form y=mx +b for this function is :
y=1/2 x +10
y = 1/2x + 10 ; Find the slope then find the y-intercept.

(4,-20)
midpoint ((x1+x2)/2, (y1+y2)/2)
Let S be (x,y(
(0+x)/2=2, solve for x, x=4
(4+y)/2=-8, solve for y, y=-20
