Elena wants to earn at least $180 a week to help her parents with bills. She determines that she can charge $15 an hour to babysit and can earn $10 an hour bagging groceries. She can only work 13 hours per week. Write and graph a system of linear inequalities that shows the number of hours she can work so she can help her parents. Use x for the number of hours babysitting and y for the number of hours bagging groceries. Choose the graph that shows all the possible combinations. List two possibilities.

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

with btw u said 100pts but it clearly says

i answerd and just got 10pts
