Answer:
(15,16)
Step-by-step explanation:
C=halfway between A to B
A to B on the x axis goes across by 24
24/2 =12
3+12=15
A to B on the y axis goes up by 28
28/2 = 14
2+14=16
(15,16)
When you subtract a negative, it changes it to adding a positive.
= -2.5 - (-3.25)
= -2.5 + 3.25
= 0.75

We know that
to find the equation of a line i need two points
let
point A-----> (-21,10)
point B-----> (-28,14)
step 1
find the slope m
m=(y2-y1)/(x2-x1)-----> m=(14-10)/(-28+21)----> m=-4/7
step 2
find the equation of a line with
m=-4/7 and the point A (-21,10)
y-y1=m*(x-x1)------> y-10=(-4/7)*(x+21)---> y=(-4/7)x-12+10
y=(-4/7)x-2
step 3
find x intercept
for y=0
y=(-4/7)x-2------> 0=(-4/7)x-2-----> 4/7x=-2----> x=-14/4----> x=-3.5
the x intercept is (-3.5,0)
step 4
find the y intercept
for x=0
y=(-4/7)x-2--------> y=-2
the y intercept is (0,-2)
the answers arethe x intercept is (-3.5,0)the y intercept is (0,-2)
