How do you find rate of change? O change in y/change in x. change in x/change in y

Rate of change is used to mathematically describe the percentage change in value over a defined period of time. (I looked that up)

So the rate of change is the slope and slope is the ratio of change between any 2 points on a line.

Slope measures the steepness of a line.

Slope is the ratio of the vertical change, called the rise, to the horizontal change called the run between any 2 points on the line.

Slope is written as a fraction in simplest form. 5/10=1/2

Variable for slope: M.

Reply for any more questions, also sorry for a slow response. I thought a lot.  

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?
