A local hamburger shop sold a combined total of 568 hamburgers and cheeseburgers on Saturday. There were 68 more cheeseburgers sold than hamburgers.

How many hamburgers were sold on Saturday?

Use algebra:

Let x be the number of burgers sold.

We know that then for a fact that:

x + (x+68) = 568

Since the number of total burgers sold is 568

Then, we know that:

2x + 68 = 568

Subtract 68 from both sides:

2x = 500

Divide both sides by 2,

Answer is 250

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
