Your classmate wants you to check her work. She is working on a math question that asks her to determine the slope of a line giv

en on a graph. You can see that the graph is a line, and that the line is increasing. Your classmate says that it’s a positive slope but you are not sure of the explanation. She tells you that she went down 5 units and to the left 3 units to the next point on the line to determine the slope. Determine if your classmate is correct and explain why or why not.

The answer of my classmate that the line has a positive slope is CORRECT. This is because the line is most likely to lean to the right. The slope can be calculated through the equation, 
                                    slope = rise / run = change in y / change in x
If both are negative, the slope is POSITIVE.

Each​ month, a shopkeeper spends 7x+19 dollars on rent and electricity. If he spends 5x−2 dollars on​ rent, how much does he spe
insens350 [35]

The shopkeeper spends 2x + 21 dollars on electricity

The amount the shopkeeper spends on electricity less than​ $100 is:

x < 39.5

<h3>What is a linear inequality?</h3>

Linear inequality explains the range of values that a variable represents.

Total amount spent by the shopkeeper = 7x + 19

Amount spent on rent = 5x - 2

Total amount spent = Amount spent on rent + Amount spent on electricity

(7x + 19)   =  (5x - 2 )  + Amount spent on electricity

Amount spent on electricity = (7x + 19) - (5x - 2)

Amount spent on electricity = 7x - 5x + 19 + 2

Amount spent on electricity = 2x + 21

For which​ value(s) of x is the amount the shopkeeper spends on electricity less than​ $100?

Amount spent on electricity  <  100

2x  +  21  <  100

2x  <  100  -  21

2x  <  79

x  <  79/2

x  <  39.5
