The general formula: y=mx+b
(6,2) ⇒ x=6,y=2
m=3
b=?
2=3*6+b
2=18+b
b=-16
<u>y=3m-16</u>
So, its 18.5 per person

80/5=16
18.5-16=2.5
They would each save 2.5 dollars each.</span></span>
Answer:
m = -2
y-intercept = 4
Step-by-step explanation:
m = y2-y1/x2-x1
so
m = -2-4/3-0
=-2
y=mx+b
Substitute the coordinates into the equation to find b
4=-2(0)+b
4=b
so y intercept is 4
y=-2x+4
