Hello : let
A(5,22) B(2,13)
the slope is : (YB - YA)/(XB -XA)
(13-22)/(2-5) = -9/-3
an equation is : y=ax+b a is a slope
y = 3x +b
the line through point A (5,22) :
22 = 3(5)+b
b = 7
the equation is : y =3x+7
G is<span> the centroid it means that BG/FG=2 (G divides the median with this ratio)
3x+6/2x-1=2
3x+6=4x-2
x=8
then AG=26 then GE=13 so AE=39</span>
.3125 expressed as a fraction is 5/16
Answer:
slope: 3
y-intercept: (0, -1)
Find slope:
Here given points are: (0, -1), (3, 8)
When finding y-intercept, the value of x is 0. Here given y is -1 when x is 0.
y-intercept: -1 or (0, -1)
