Answer:
y= (-1/2)x+(5/2)
Step-by-step explanation:
equation point slope
(y-y1)=m(x-x1)
y-3 = -1/2(x+1) add -3 to both sides and distribute
y=( -x/2) +(-1/2)+3 rewrite 3 as 6/2
y=(-1/2)x +(-1+6/2) solve
y= (-1/2)x+(5/2)

This is the same as,

Comparing to

We have
a=2, b=3,c=-8
Using the quadratic formula, the solution is given by:

We substitute the values to get,


The positive root is

to the nearest hundredth.
13: 72.25
14: 52
For 14, you need to split the figure into a triangle and rectangle.
