Graphing Predictions and Equations for 6th Grade

A graph shows the number of books read by a student over 5 months. If the line on the graph rises steadily, how many books do you predict the student will read in the 6th month?

• The same number of books as the previous month.

• The same number of books as the first month.

• More books than the previous month.

• Fewer books than the previous month.

The graph displays the temperature in a city over a week. If the temperature is increasing by 2 degrees each day, write an equation to represent the temperature on day 'x'.

• T + 2x

• T + x

• T - 2x

• 2T + x

A car rental company charges a flat fee of $20 plus $0.50 per mile driven. If a graph shows the total cost for different mileages, how much would it cost to drive 100 miles?

• $70

• $100

• $90

• $50

The graph shows the number of customers at a store over a day. If the number of customers increases by 10 every hour, write an equation to represent the number of customers after 'h' hours.

• C + 10h

• C - 10h

• C * 10h

• C + 5h

A school tracks the number of students participating in sports over the year. If the graph shows a linear increase, predict how many students will participate after 6 months if there were 30 students at the start.

• 75

• 90

• 60

• 45

The graph indicates the amount of water in a tank over time. If the water level decreases by 5 liters every hour, write an equation to find the water level after 't' hours.

• W / t

• W - 5t

• W - 10t

• W + 5t

A farmer sells apples and the graph shows the relationship between the number of apples sold and the total revenue. If the slope of the line is $2 per apple, how much revenue is generated from selling 50 apples?

• $100

• $150

• $50

• $200

The graph shows the distance a runner covers over time. If the runner maintains a steady pace, how far will they have run after 30 minutes if the graph indicates a distance of 5 km in 15 minutes?

• 20 km

• 7.5 km

• 15 km

• 10 km

A bike shop tracks the number of bikes sold each month. If the graph shows a steady increase of 3 bikes per month, write an equation to represent the number of bikes sold after 'm' months.

• bikes_sold = 3 * m

• bikes_sold = 3 * (m + 1)

• bikes_sold = m + 3

• bikes_sold = 3 + m

The graph illustrates the growth of a plant over weeks. If the plant grows 2 cm each week, predict its height after 8 weeks if it started at 10 cm.

• 26 cm

• 30 cm

• 20 cm

• 15 cm
