• slope: 5   y-intercept:  (0,3) 

• slope: 3/2   y-intercept:  (0,3) 

• slope:  4  y-intercept:  (0,3/2)

• slope: 1/5   y-intercept:  (0,5)

What is the function for the line?

Pick two points and put them in the spreadsheet to find "m" and "b", then insert them into the formula y=mx+b.

• y=2x+ 4/3

• y= -4/3 x + 2

• y= 3/4 x -2

• y= -2x + 2

Is the graph proportional or non proportional?

• Proportional because it is a straight line and passes through the origin (0,0).

• Non-Proportional because it doesn't pass through the origin (0,0).
