2. A student finds the slope of the Ine between (14, 1) and (18,17). 1-17
She writes
What mistake did she make?
18 - 14
She should have added the values, not subtracted them.
O She used y-values where she should have used x-values.
O She did not keep the order of the points the same in the numerator and the denominator.
O She mixed up the x- and y-values.
