Linear Functions and Equations

Which equation best represents the graph ? 

• y = 1.25x+2, because the y-intercept is 2 and the slope is 1.25. 
• y = 2x+1.25,  because the  slope is 2 and  the  y-intercept is 1.25.  
• y =  1.25x, because the  slope is 1.25  and the relationship is proportional.  
• y  =  2x ,  because the  y-intercept  is  2. 

Which table(s) are nonlinear?

• Table 2, only

• Tables 2 and 3, only

• Tables 1 and 2, only

• Tables 2 and 4, only

Which answer choice is true?

• The table represents a linear function because there is a pattern for the x-coordinates and y-coordinates.
• The table represents a linear function because the ratio of the change in the y value and the change in the x value is constant.
• The table represents a nonlinear function because the ratio of the change in the y value and the change in the x value is not constant.
• The table does not represent a function because there is more than one output for at least one input.
