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

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.
