Graphing Linear Equations in Quad. 1 (It's Not Pointless!)

Henry used a number machine to create ordered pairs of numbers. Each number he put into the machine, (x) came out as a different number, (y) based on a rule. Some ordered pairs from Henry’s machine are shown. Which graph corresponds with the ordered pairs generated by Henry's machine?

Henry used a number machine to create ordered pairs of numbers. Each number he put into the machine, (x) came out as a different number, (y) based on a rule. Some ordered pairs from Henry’s machine are shown. Which of the following is an equation for the rule Henry's number machine is based on?

• $y=x-2$

• $y=2x-4$

• $y=\frac{1}{2}x$

• $y=x+1$
