Mofor had $21 to spend on two notebooks. After buying them he had $13. How much
did each notebook cost?
Two-step equations

Step-by-step explanation:

21-13=8

8÷2=4

A note book costs 4$

the unit price of the notebooks:  $4

Step-by-step explanation:

Mo starts with $21 and finds himself left with $13 after buying the notebooks.  Subtracting $13 from $21 results in $8, the amount he spent on two notebooks.  Dividing $8 by 2 yields the unit price of the notebooks:  $4

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

answer: r there any options?
