Answer: The slope is 2
Step-by-step explanation: For questions like these, find 2 points on the graph that are on whole numbers, for example (10,60) and (20,80). Then use the formula y2-y1/x2-x1 to solve for the slope, which would be the same thing as rate of change. 80-60/20-10 which equals 2. The slope would be 2.

Answer:
26
Step-by-step explanation:
First substitute x for 9
Then your problem is m(9)=2(9)+8
Now it is m(9)=18+8
Then add 18 and 8 for 26
