The answer to your question is -2.
If 1 inch represents 20 miles, then 5 inches should represent <em>5 times as many miles</em>, or 20 x 5 = 100 miles.
Answer:
4y = -x + 9

First you want to find the length and width of the rectangle using the distance formula:
d=√(x2-x1)²+(y2-y1)²
AB=√(6-3)²+ (-2 - -2)²
AB=√3² + 0
AB=√9
AB=3
BC=<span>√(6-6)²+ (5 - -2)²
BC=</span>√0 + 7²
BC=√49
BC=7
We can find the area by multiplying these two distances together:
A=(3)(7)
A=21 units²
Mai: y = 7x + 15
Priya: y = 8.5x
7x + 15 = 8.5x
15 = 1.5x, x = 10
It takes 10 hours
