I missed my class and don’t know how to do this

Answer:
1. 4/5
Step-by-step explanation:
remember:
slope = rise/run
slope = y2 - y1 / x2 - x1
to solve for #1:
you have your givens points, (4,5) and (6,9)
you can label 4 as x1 and 5 as y1, 6 as x2 and 9 as y2.
now plug in those numbers to the equation y2 - y1 / x2 - x1.
9 - 5 / 6 - 1 = 4/5 which is your answer.
now do the rest like that and you should have your answer! :)
hope this helps.
