Use y = mx + b.

<u>m represents the slope of the line.</u>

the slope equals rise over run.

in other words, count the number of vertical and horizontal units from one point to another point on the line.

if you have the y-intercept and a point, you can also solve for m.

<u>b represents the y-intercept.</u>

find the point on the graph where x = 0.

b is the value of y.

for example, if the y-intercept was (0,4) then b would equal 4.

<u>x and y represent a point on the graph.</u>

pick any point on the graph and plug it in.

for example, if the point (1,2) is on the graph then x = 1 and y = 2.

A truck's gas tank holds 50 gallons of gas. if one gallon takes 30 seconds to pump, how many minutes will it take to fill the em
umka2103 [35]
To find how long it will take to fill the tank, you can use the idea that every 30 seconds will get you one gallon closer to being full.

This means to fill 50 gallons, you will need 50 groups of 30 seconds.  

50 x 30 = 1500 seconds

1500/60 = 25 minutes.

It will take 25 minutes.  

You could also think of it as filling 2 gallons every minute.  It would take 25 of these.

Patrick wants to buy a rug for a section of his living room. When he approaches a rug vendor, which measurement would be most ap
Kazeer [188]
Usually, rugs have a rectangular shape, therefore the section of the living room that Patrick wants to cover is a rectangle.

The area of a rectangle can be found by multiplying the length and the width of the rectangle:
A = l × w

Hence, the most appropriate measurements Patrick should provide are the length and the width of the section of his living room he wants to cover.

Twenty people each had 36 carrots. How many carrots are there altogether?
elena-s [515]

You know that there are 25 people and each person had 36 carrots. To find how many carrots everyone has in total, you have to multiply 25 by 36.

25 times 36 is 900.

There are 900 carrots altogether.
