Question

How do you find the slope of a line parallel to `y = 5 - 2x`?

Answer 1

All lines parallel to `y=5-2x` have a slope of `color(green)((-2))`

Explanation:

All parallel lines have the same slope

`y=5-2x`
can be written as `y=color(green)((-2))x+color(blue)(5)`
which is the slope-intercept form for a line with
`color(white)("XXX")`slope`=color(green)((-2))` and
`color(white)("XXX")`y-intercept`=color(blue)(5)`
