A student finds the slope of the line between (8,7) and (1,4). She writes 17-4/1-8. What mistake did she make
Ksju [112]

Answer:

It's supposed to be 4-7/1-8

Step-by-step explanation:

The formula for slope is y1 - y2 / x1 - x2 (subscript). So you would take the y value from (8,7) which is 7, and subtract by the y value from (1,4), which is 4. You do the same for the x values and you get 7-4/8-1, which is 3/7.
