What do the values of m and b represent in the equation y=mx+b?

m is the slope and b is the y-intercept

The value of m is the slope

If you have a equation like this:

y = 2x

2 is your slope. Your slope is always rise/run. This mean that for this equation you are going to rise 2 and run 1 since x is going to be equal to 1

The value of b is the y-intercept

For the equation above, you can see no b which means that you start at (0,0)

In this second equation:

y = x + 2

The b is equal to 2, so the y - intercept is 2 and you are going to start at the point (0,2)

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180
