Hi, I am very happy to help you! I know how to do this! Super Easy!!!!
You will have 2 different x's and they are 3 and 6.
You will have 2 different y's and they are 16 and 19.
In order to get m, you have to subtract y2-y1/x2-x1=m
So the answer would be 1.
In order to solve b, you have to choose one of your given coordinate points and plug them in for x and y and plug in your m, which is 1.
I will be choosing the coordinate points (3,16)
So our b is 13.
So our answer using the form is y=1x+13
