The x and y intercepts of a line are when and respectively.

The given equation is:

(1) Why c and d are the intercepts

We have:

Multiply through by cd

A linear equation is represented as:

Where:

x intercept

y intercept

So, by comparing to

The x-intercept

The y-intercept

(b) How the intercepts are related to c and d?

In (a) above, we have:

The x-intercept

The y-intercept

When

We have:

Divide by c

---- the y-intercept

When

We have:

Divide by d

---- the x-intercept

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
