Answer:
y=-2x+6
Step-by-step explanation:
So you know the perpendicular gradient is -2 so the equation so far is y=-2x+?
Find the midpoint of AB which is:
(3,0)
Using this, plug it into the equation you've formed:
0= -6 + ?
? = 6
So the equation of the perpendicular line is y=-2x+6
You get it by cross multiplication
10×9÷3=30 and if you want to check
30 over 9 =3.333
10 over 3 = 3.333
8=32%
divide both sides by 32
1/4=1%
times 100 both sides
100/4=100%
25=100%
25 total dogs and cats
