An equation in the point-slope form to represent the total cost y for x tickets is
Let the cost of ticket be C
Let the number of tickets be x
The coordinate for the cost of a ticket will be written as: (x, C)
If the cost for one ticket to a jazz concert is $7.50, this is represented in coordinate form as (1, 7.50)
If two tickets cost $15, his is represented in coordinate form as (2, 15)
Get the slope of the equation
Get the equation in point-slope form
Substitute the slope and one of the point into the formula:
Hence an equation in the point-slope form to represent the total cost y for x tickets is

-5 it’s always gonna be the last # in this type of equation: y=mx+b. (-5 is in the place of b so it’s the y int)
(5/4) / (2/3)
= 5/6
therefore: he has run 5/6 miles so far
