Joelle is working on a school report in a word processor. she wants to place an oversized image which is 30.51cm wide so that it appears centered on the page. the width of the page is 21.59cm . in the program, horizontal positions to the right of the leftmost edge of the page are positive what horizontal position for the left edge of the image should joelle use to center the image?

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.

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
