Answer: y=1.6x+6; $62
Step-by-step explanation: Work provided in the attached image. To solve this problem, the slope intercept formula can be used, which is y=mx+b. We do not know m or b yet, so we have to solve for it. To find m, you need to divide the change in the y value by the change in the x value. In this case, the y values are represented by the cost and the x values are represented by the cost. So, you can do (22-14)/(10-5) to get 1.6. Again, this is your m value. Then, to find b, you can put a point from the table in the equation y=1.6x+b. The b value would be 6. So, your equation would be 1.6x+6. To find the cost after 35 miles, simply just plug in 35 for the x value. You would get $62. Hope this helped!
