The ratio of ed’s cars to pete’s cars was 5: 2 at first. after ed gave 30 cars to pete, they had an equal amount of cars each. how many cars did they have altogether?

this is answer of 144 cubic meters

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
