This is what you need to find the answer
$29.95+$1.50(533)+(533/16)($2.15)
=$901.07
Three or more points are collinear, if slope of any two pairs of points is same. With three points A, B and C, three pairs of points can be formed, they are: AB, BC and AC. If Slope of AB = slope of BC = slope of AC, then A, B and C are collinear points
Y=(c-ax) divided by b
The (c-ax) is divided as a whole over b. Thus reaching an answer for y.
The slope is 4/6 because its going up by 4 over by 6 .hope this helps
