System of linear equation for graph below

Mathematics
1 answer:
Andrej [43]3 years ago
5 0

Answer: See below

Step-by-step explanation:

For the line on top, we know the slope is negative because it is going down. We can find the slope by counting how much the point goes down and to the right. Y-intercept is the point on the y-axis.

slope: -3

y-intercept: 2

Now that we have the slope and y-intercept, we know the equation is y=-3x+2.

For the second line, we know the slope is positive because it is going up. Since slope is rise/run, we can see it rises 1 unit and runs to the right by 2 units. Y-intercept is the point on the y-axis.

slope: 1/2

y-intercept: -5

With our slope and y-intercept, we know our equation.

y=1/2x-5

Mike earns $15 for each hour he work plus a $25 bonus. How much does he earn in 10 hours of work?
MakcuM [25]
<h3>Hello there!</h3>

We are trying to find how much Mike earns when he worked for 10 hours

Lets make an equation out of the given information in the question.

We know that:

  • Earns $15 each hour
  • $25 bonus

We would format it as y = mx + b

Our equations would be y = 15x + 25

"x" being the amount of hours he worked

We know that he worked 10 hours, so we would plug 10 into x.

Then, we can solve.

y = 15(10) + 25

y = 150 + 25

y = 175

<h3>Answer: $175</h3><h3>I hope this helps!</h3><h3>Best regards,</h3><h3>MasterInvestor</h3>
