Question

Complete the table for the function y=2x.
x y
–
1
0
1
2
Now, graph the function.
Plot two points to graph the function.

Answer 1

Complete table (y = 2x):

x = -1 → y = -2
x = 0 → y = 0
x = 1 → y = 2
x = 2 → y = 4

Two points to plot: (0, 0) and (1, 2).
Plot those on the coordinate plane and draw the straight line through them (this line will also pass through (-1, -2) and (2, 4)).
