An illustration shows the first quadrant of a coordinate plane titled Minutes played vs Points scored. The x-axis shows Minutes played and ranges from 0 to 40 in increments of 4. The y-axis shows points scored and ranges from 0 to 30 in increments of 5.
Thirteen points are plotted on the graph. The points are plotted at approximate coordinates left parenthesis 0 comma 0 right parenthesis, left parenthesis 4 comma 2 right parenthesis, left parenthesis 9 comma 8 right parenthesis, left parenthesis 12 comma 7 right parenthesis, left parenthesis 12 comma 11 right parenthesis, left parenthesis 16 comma 10 right parenthesis, left parenthesis 18 comma 14 right parenthesis, left parenthesis 20 comma 19 right parenthesis, left parenthesis 22 comma 15 right parenthesis, left parenthesis 24 comma 18 right parenthesis, left parenthesis 27 comma 29 right parenthesis, left parenthesis 33 comma 20 right parenthesis, and left parenthesis 33 comma 22 right parenthesis. An upward slanting line starts at left parenthesis 0 comma 0 right parenthesis and continues to left parenthesis 18 comma 13 right parenthesis.
Your coach gathered data on the number of minutes each player played in the game and their points scored. The slope is .7. Interpret the meaning of the slope.
Option 1: The slope means that, for every .7 minutes played, 1 point was scored.
Option 2: The slope means that .7 points were scored for every 1 minute played.

Option 1: The slope means that, for every .7 minutes played, 1 point was scored.
That's wrong
Option 2: The slope means that .7 points were scored for every 1 minute played.
Your teacher surveyed the class to determine the number of hours that each student spent on social media. Your teacher created a table and scatterplot graph that displayed the number of hours and the average final grade based on the hours. The trend line (equation) for the data is y = −7.2x + 98.9. Interpret the slope. How many points does the average final grade decrease for 1 hour on social media?
The slope is -7.2. This means that for every 1 hour spent on social media, the average final grade decreases by 7.2 points.
Your teacher surveyed the class to determine the number of hours that each student spent on social media. Your teacher created a table and scatterplot graph that displayed the number of hours and the average final grade based on the hours. The trend line (equation) for the data is y = −7.2x + 98.9. Interpret the y -intercept. What is the average grade if a student was on social media for 0 hours?
The y-intercept in the equation y = -7.2x + 98.9 is 98.9. This means that if a student was on social media for 0 hours, the average final grade would be 98.9.
Your company asked you to analyze the investment of their advertising campaign. You create a scatterplot graph of the advertising dollars spent on advertising, x, and compare it to the revenue generated, y, for January to December of the campaign. You find the equation of the trend line to be y = 2.53x + 43. Predict the revenue generated if your company invests $200.00 in advertising. Write the revenue in dollars and cents.
The revenue generated for a $200.00 investment in advertising is $__.
First, substitute $200.00 for x in the equation y = 2.53x + 43.
y = 2.53(200) + 43
y = 506 + 43
y = 549
Therefore, the revenue generated for a $200.00 investment in advertising would be $549.00.
You work for a manufacturing company on a production line that manufactures cell phones. You are paid $30 a day plus $0.75 for each phone that you assemble. Predict your wages if you assemble 100 phones in one day, using the equation of the trend line y = 0.75x + 30, where x is the number of phones assembled in one day and y is the total wages. Write your wages in dollars and cents.
Your wages are $
First, substitute 100 for x in the equation y = 0.75x + 30.
y = 0.75(100) + 30
y = 75 + 30
y = 105
Therefore, your wages for assembling 100 phones in one day would be $105.00.
