What is the slope of the line?

Step-by-step explanation:

If you start at (2,0) you go up 3 and to the right 1. The reason for this is because you need to find points that intersect perfectly to find the slope. I really hope this makes sense. Im not sure how else to explain it. Have a good day :)

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
