Which equation best represents the relationship shown on this graph?
y = 25 + x
y = 25x
y = 25
answer not here
Which statement describes the relationship between x and y in these two equations?
Y = x - 2
Y = 2x
In y = x - 2 and in y = 2x, the value is 2 less than the value of x.
In y = x - 2 and in y = 2x, the value is 2 times the value of x.
In y = x - 2, the value of y is 2 less than x, and in y = 2x, the value of y is twice the value of x.
In y = x - 2, the value of y is 2 times the value of x, and in y = 2x, the value of y is 2 less than the value of x.
Which equation best represents the relationship in this table?
y = 9.6x
y = 10.6x
y = 9.6
y = x + 9.6
Which values are the dependent variables?
y- values
x-values
The equation below describes a relationship between x and y.
y = 2x
You can use the table below to help select the graph that shows this relationship.

Jose travelled at a rate of 0.25 miles per minute. Which equation represents this relationship?
(Remember you can convert a fraction into a decimal, if needed)
y = x/4
y = x + 0.25
y = 1⁄4x
y = 0.25
y = 3x
y = 3 + x
y= x + 6
x = 3y
Which situation can be represented by the equation y = 5x?
(Remember the important operation words: x, -, +)
