To graph this problem you have to place a point on 20 and go down 5 and go over 2 to the right and do the opposite, (5 up over 2 on the left) and then you just connect the dots.
This is basically just saying you'll go outside Tuesday because it's sunny. Sunny weather is nice weather.
So slope is rise/run so 5/1 would be your slope. Hope this helped.
7*(x+5)*(x -5) that is your answer right there
