First step you would have to do would be to times 35 by 12 to see how much you would have to pay for 12 months.
35 x 12 = 420
Then, as you said, you a down payment of 600 so then you'd add.
600 + 420 = 1,020.
So the total cost of the computer would be $1,020.
The slope is 4. It's right there in the problem. The equation underneath that is y=mx + b. M, in this case 4 or 4/1 is the slope. And 5 is the y intercept or where the line crosses the y axis.
If RS arc is = to the RS central angle then the RS arc would be 20 degrees, but if the RS is on the Circumference then the RS arc would be 40.
I think that the answer is m = -1
