Esther is participating in a walk-a-thon. She will raise 5 dollars for her charity for each lap she walks. Let l = the number of laps she walks

Let d = the number of dollars she raises

independent variable = number of dollars; dependent variable = number of laps
independent variable = number of charities; dependent variable = number of people
independent variable = number of dollars; dependent variable = number of people
independent variable = number of laps; dependent variable = number of dollars

answer d

Step-by-step explanation:

I took the assignment and got it right :)

it has the same slope and a different y-intercept

hope this : )

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
