Question

A student finds the slope of the line between (8, 17) and (1, 4). She writes 17-4/1-8 What mistake did she make?

Answer 1

She used y wheremail she should have used x

Answer 2

The answer is actually *C. She mixed up the x and y values.*  x2-21/y2-y1 is the equation you need to solve for slope. Therefore the proper equation should be

1-8/17-4
