Question

2. If you were to graph the line y = 2x-1 using a t-chart, list the five ordered

pairs that would go in the chart shown.

Answer 1

(-2, -5)

(-1, -3)

(0, -1)

(1, -1)

(2, 3)

Explanation:

To do this you simply put in an input for x and then solve and you will get your y.

We'll use

x= -2 for this input

y=2(-2)-1

y=-4-1

y=-5

(-2, -5) Is one ordered pair

We'll use

x= -1 for this input

y=2(-1)-1

y=-2-1

y=-3

(-1, -3) Is another ordered pair

We'll use

x= 0 for this input

y=2(0)-1

y=0-1

y=-1

(0, -1) is another ordered pair

We'll use

x= 1 for this input

y=2(1)-1

y=2-1

y=1

(1, -1) is another ordered pair

We'll use

x= 2 for this input

y=2(2)-1

y=4-1

y=3

(2, 3) is the last pair I'll use today.

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
