8U1Pt 2 Linear Relationships Review

Each relation shown defines y as a function of x. Which function has the greatest rate of change?

Denny believes that the function $$y=2x$$ is linear, while Odette believes that it is nonlinear. Who is right and why?

Does the set of ordered pairs { (1, 1) , (2, 1), (3, 3) , (4, 3) , (5, 3) } define a function?

Look at the linear equation graphed. If x = 16, what value of y is a solution to this equation?

Which equation represents the line shown in the graph?

The graph shows a linear relationship that represents the cost of renting a motorized bicycle based on the number of hours for which the motorized bicycle is rented. Which of these is true?

When South View Middle School opened in 2010, there were 90 faculty members. In 2012, there were 94 faculty members. Which function models this situation and why?

Which coordinate plane represents the linear relationship $$2x-4y=-8$$ ?

Janet teaches piano lessons for $18 an hour and babysits for $12 an hour. She wants to buy a new tablet that costs $216. All the ways she can combine p hours of piano lessons and b hours of babysitting to earn $316 are represented by this equation.

$$18p+12b=216$$

Plot the line on the graph that represents all of the solutions of the equation.
