If a gas tank can hold 30 gallons, how many gallons does it contain when it is three-firth’s full?

18 gallons

Step-by-step explanation:

We require to calculate of 30 gallons

Multiply 3 by 30 and divide by 5, that is

= = 18 gallons

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
