Are the points on the same line? If you are given 3 or more points and asked if they lie on the same line: Check the slope from one point to the next If all of the slopes are the same, they are on the same line. If not, the do not lie on the same line **same slope, same line

Do the points lie on the same line Do the points lie on the same line? If so, write the equation of the line. A) B)
