Answer:
5)y=2x 6)y=12x 7)y=3x-2 8)y=1/4x+2
Explanation:
Look at the y-intercept first if crosses the origin then don't need to write anything. If it does you add it after the slope.
To find slope you can count how many units up or down it does and how many left or right.
Then write i as rise/run.
Hope this helps
