How do u get the slope?

Answers

Answer 1

Slope in fraction form = 3/2

Slope in decimal form = 1.5

============================================================

Explanation:

That table shows the two points (x1,y1) = (-14,-18) and (x2,y2) = (-10,-12).

Each row is a different point.

To find the slope, we subtract the y values to get y2-y1 = -12-(-18) = -12+18 = 6

Then we subtract the x values to get x2-x1 = -10-(-14) = -10+14 = 4

Lastly, we divide the two differences: ydiff/xdiff = 6/4 = 3/2

The slope in fraction form is 3/2, which is equivalent to the decimal form 1.5

------------------------

If you want, you can apply the slope formula like so

m = slope

m = rise/run

m = (change in y)/(change in x)

m = (y2-y1)/(x2-x1)

m = (-12-(-18))/(-10-(-14))

m = (-12+18)/(-10+14)

m = 6/4

m = 3/2

m = 1.5

We effectively are following the same as steps as before, but in this format, it's more of what you might have on your homework if you were to show the step-by-step process. You could also do a visual graph approach as a different option. Often in math there are multiple ways to get the answer.

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile.

1. How far can the car travel with 15 gallons?

Answers

Answer:

525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallongallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

distance = mile/gallon x gallons

distance =35 miles/gallon x 15 gallons = 525 milles

The car can travel 525 miles on 15 gallons of gas.
