Mariulka [41]

The percent increase is 80%

Step-by-step explanation:

Percent increase is given by:

$Percent\ Increase=\frac{Increase}{Previous\ value}*100\\While\\Increase= New\ value - Old\ value\\$

Here

New value = 36

Old Value = 20

Increase = 36-20 = 16

So,

$Percent\ increase=\frac{16}{20}*100\\=0.8*100\\=80\%$

The percent increase is 80%

Find the slope and the y- intercept of the line y=2x-6

Alchen [17]

Answer:

The slope is 2 and the y-intercept is -6

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is unit rate or the slope of the linear equation

b is the y-intercept or initial value (value of y when the value of x is equal to zero)

In this problem we have

$y=2x-6$

therefore

the slope is equal to

$m=2$

and

$b=-6$

Verify

For x=0

$y=2(0)-6=-6$ ---> is ok
