Yeah, where I live, to find the slope (or as we call it, the gradient), you just have to do the two y values subtracted from each other, over the two x values subtracted from each other. The important thing is to remember that if you subtract the first y value from the second (so, 12 - 8), you have to do the same thing for the x (6 - 2)

=

= 1.
The slope is 1.
Answer: make it bigger~
Step-by-step explanation:
15 miles/hour x 2/3 hour = 30/3 = 10 miles
30x-18 because 6•5x=30x and 6•3=18.
