The answer is C. b=2. I found the answer by first finding the slope. To find the slope i found the difference of the y values and divided that by the difference of the x values. 14-5/4-1 This simplifies down to: 9/3 which equals 3. I then plugged this into the slope intercept form: y=mx+b to get y=3x+b The next step would be to plug in the values of one of the points to solve for b. The point I choose was (1,5). By plugging this point into the equation i got 5=3(1)+b which simplifies to 5=3+b which means that b=2
