How do you graph #y = x - 2# by plotting points?

Answer 1

Avery Alexander

See answer below

Given: #y = x - 2#

The #x# is the independent variable. This means we can select any #x# value and calculate the corresponding #y# value.

#ul(" "x " "|" "y" ")# #" " -2" "| -2-2 = -4# #" "0 " "|" " 0 - 2 = -2# #" "3" "|" "3-2 = 1# #" " 6" "| " "6-2 = 4#

graph{x-2 [-10, 10, -5, 5]}

To graph the equation y = x - 2 by plotting points, you can select several values for x, plug them into the equation to find the corresponding values of y, and then plot these points on a coordinate plane. For example:

When x = 0, y = 0 - 2 = -2 When x = 1, y = 1 - 2 = -1 When x = 2, y = 2 - 2 = 0 When x = 3, y = 3 - 2 = 1

Plotting these points on a coordinate plane and connecting them with a straight line will give you the graph of y = x - 2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
