Mai had 8 packs of pens. each pack had 10 pens. she gave 5 packs to ervin and 3 packs to sara

Assuming you want the amount of pens that Mai has left, the answer is 0.

Step-by-step explanation:

Mai has 8 packs of pens. She gives 5 away to Ervin and 3 away to Sara. In total, she gives away all 8 packs (because 5+3=8).

She started with 8, and gave away 8. This resulted in her having 0 packs left (because 8-8=0).

I hope this helps!

x=30

step-by-step explanation:

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
