Which equation represents a proportional relationship that has a constant of proportionality equal to 0.7
y/x = 7/10
Which table represents the same proportional relationship as the graph?
A
Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to 7/25. She writes the equation y = x + 7/25. What error is Roni making?
She should have written y = 7/25x so that x and y have a constant quotient.
Which equation represents a proportional relationship that has a constant of proportionality equal to 4/5?
y = 4/5x
Jacqueline reads 25 pages every night. Which graph correctly displays y, the total number of pages that Jacqueline has read after x days?
D
Rita is developing an equation that will represent the same proportional relationship as the graph.
How will the ordered pair help her when she finds the equation?
The quotient of the coordinates will be a coefficient in the equation.
Which equation represents a proportional relationship that has a constant of proportionality equal to 2?
y = 2x
Which equation represents a proportional relationship that has a constant of proportionality equal to 1/5?
y = 1/5x
Which equation represents the relation that is shown in the graph?
y = 7/2x
