Answer:
The second option
Step-by-step explanation:
To solve this, you should convert both rates to equations, with y being the total fare, and x being the number of miles. The rates of both use the format y=mx+b (where m is the amount per mile and b is the flat rate, or original rate).
By subbing in the values for m and b, you get y=2x+4 for A and y=3x+5 for B. This is the second option.
**This question involves writing linear equations, which you may wish to revise. I'm always happy to help!
Answer:
The second one, question 4, would be C, y = -2x + 16
Step-by-step explanation:
You're trying to make an equation out of the information on the graph.
So, start with the format y = mx + b.
The variable m represents the slope. Use rise/run. I chose to use the points (0, 16) and (2, 12).
You would end up with a rise over run that looks like this: 4/2. Simplified, the slope would be 2. Because this line is moving downwards, your slope is negative.
So far, you have y = -2x + b.
The variable b represents the initial value, or where the line first touches the y-axis. You can see that the initial value is 16.
Plug that in. y = -2x + 16.
Hope this helps! Sorry I couldn't answer both, good luck on that test! <3
