Driving at a speed of 75 mph, a Mini Cooper's fuel efficiency is 29 miles per gallon. If the driver slows to
a speed of 60 mph, he will have a fuel efficiency of 34
miles per gallon. What is the average rate of change of
the fuel efficiency as the speed drops from 75 mph to
60 mph?

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

What is the slope of the line shown below?

Which equation shows y= 3 4 x− 5 2 in standard form? a 4x−3y=10 b 3x−4y=10 c 3x−4y=−10 d 4x−3y=−10
