Answer:

y=3x+(0,4.5)

Step-by-step explanation:

i did this in my head, but the difference between -8 and 7 is 15. the difference between 2 and 7 is 5. it's rise over run so (15,5). that simplified is (3,1)/3. that is the slope. now you need a graph to see the y-int. the y-int is around 4.5.

Answer:

$\$675$

Step-by-step explanation:

Remember that

$100\%-35\%=65\%=65/100=0.65$

Let

x ----> the total cost of the books

we know that

The total cost of the book multiplied by 0.65 must be equal to $438.75

The linear equation that represent this situation is

$0.65x=438.75$

solve for x

$x=438.75/0.65\\x=\$675$
