Hope this helps plz hit the crown :D
You calculate it by taking the change in y's over the change in x's. So (y1-y2)/(x1-x2). You get the equation (-5 - 3)/(5 - 7) which equals 4. 4 is the slope.
The requested equation is
C(m) = 7.50 + 0.25*m,
where C(m) is the total cost (in dollars) for "m" miles.
Make the plot on your own.
15 because 3/4 is equivalent to 75% and 75% of 20 is 15.
3/4x+17=23
-17 -17
3/4x=6
/ 3/4 / 3/4
x=8
I hope I helped! ♥
