Answer:

Step-by-step explanation:
First you can find the slope of the line that would pass through those two points using the formula:
m = 
m = 
m=5/4
Now you can just plug the slope and one of the points into point-slope form for an equation of the line that will pass through both points. You can choose either point here: I'll just use the first one.
So,

(don't leave out the parentheses!)
