show the equation to solve for it, the answer, and the steps of solving the equation. you~

13 miles

Step-by-step explanation:

43-4=39      you use the inverse operation. you subtract 4 from 4, you get 39.

39/3=13       then, you also do the inverse operation. you divide 39 by 3, you        

                   get 13 as your answer.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
