Graphs 1 Complete this grid for the function y = 3x x y Answer Question 2 Substitute each value in turn into the equation. Start with the 0 as it is easier! If x = 0, y = 3 x Y = 1 If x = 1, y = 3 x Y = Do you notice that the pattern goes up in 3’s. Why is this?

Use the grid box from Q1 to plot and draw the graph of y = 3x Graphs Answer x y Now plot the coordinate pairs x x xx x This is the line y = 3x + 1 Question 3

Graphs 1 Complete this grid for the function y = 2x x y Answer Question What do you notice about the pattern again?
