How do you graph #y=7/2x-2#?
See procedure below.
The following procedure will give you the coordinates of 2 data points. As we work them out, put them on your graph paper. Then you can draw a line between them and extend them as far as you like.
Plug in 0 for y and find the value of x that satisfies the equation:
Now, solve for x.
Add 2 to both sides. Then we have
Multiply both sides by
Cancel where possible.
So we have
Therefore, you can plot a data point at
Repeat, except plug in 0 for x. Starting with:
That simplifies to
Therefore you can plot a second point at
I hope this helps,
