Question

Vera finds a quarter on the ground at (-2, 3) and then finds another one at (8, 3). Each unit on the coordinate plane represents 10 feet. What was the distance between the quarters?

Answer 1

`100" feet"`

Explanation:

`"since the coordinates have equal y-coordinates then the"`
`"distance is the difference between the x-coordinates"`

`rArr"distance "=8-(-2)xx10=10xx10=100" feet"`
graph{(y-0.001x-3)((x+2)^2+(y-3)^2-0.06)((x-8)^2+(y-3)^2-0.06)=0 [-10, 10, -5, 5]}
