Question

How do you find the slope and y intercept for `y=2x-1`?

Answer 1

Any linear equation in the form
`color(white)("XXXX")` `y = mx +b`
is said to be in the "slope-intercept form"
`color(white)("XXXX")`with has a slope of `m` and a y-intercept of `b`

`y=2x-1` is in "slope-intercept form"
and, therefore,
`color(white)("XXXX")`has a slope of `2` and a y-intercept of `(-1)`
