Question

How do you graph each set of lines on the same graph: `y=3x-5, y=3x+ 1`?

Answer 1

Graph each line but use the same graph paper/surface.
Clearly label each line with it's equation. (Use of different colors might also be useful).

Explanation:

Sample points for `color(red)(y=3x-5)`
`color(white)("XXX")color(red)({: (underline(x),color(white)("XX"),underline(y)), (0,,-5), (5,,10 ):})`

Sample points for `color(green)(y=3x+1)`
`color(white)("XXX")color(green)({: (underline(x),color(white)("XX"),underline(y)), (0,,1),(5,,16) :}`
