Maggie leaves her home and travels 4 miles
east to the grocery store. She then travels 7 miles
to the north and stops to pick up pizza. How many
miles will she travel to return home, if she takes
the most direct route? (round to the nearest tenth)

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
