Question 1000541: Joseph paddles his canoe at an average speed of 3.5 miles per hour. After 5 hours of canoeing, Joseph has traveled 18 miles.
a. Write an equation in point-slope form.
b. Write your equation in slope-intercept.
c. How far will Joseph travel in 8.5 hours?
Question: I do not know what the y, x, and m (slope) is. Could you please help me, so I can answer the other questions?

You can put this solution on YOUR website!
You can try RT=D as D=RT, and pick your variables to match "slope-intercept" form. y is distance, m is slope meaning here, RATE, and x is time. This is to be done as y=mx. This simply gives y=3.5x.

Does this work with the given data?
18=%283.5%29%285%29
18=%2815%2B%281%2F2%29%2A5%29
18=15%2B2%2B1%2F2
18=17%261%2F2-----------False, so the given data does not work and therefore is wrong.

Find out which data you have is wrong, and then you can do (a), (b), and (c). In any case, y=Rx or y=mx will be the form you want for slope-intercept form. The y-intercept is 0.
