Question

How do you find the slope and y intercept for `y=3-1.25x`?

Answer 1

The slope is `-1.25` and the `y`- intercept is `3`.

Explanation:

The equation of a line in slope-intercept form is

`y=mx+b.`

• `m` is the slope
• `b` is the `y`-intercept.

Put

`y=3-1.25x`

into that form and you get....

`y= -1.25x + 3`

So

• `m` is `-1.25`
• `b` is `3`

Have a great day!

Answer 2

Slope `= (-1.25)`
y intercept `=3`

Explanation:

One of the common ways of expressing a linear equation is in slope-intercept form.

In general the slope-intercept form looks like:
`color(white)("XXX")y=color(green)mx+color(red)b`
where `color(green)m` is the slope and `color(red)b` is the `y`-intercept.

The given equation `y=3-1.25x` can be rearranged into slope-intercept form as:
`color(white)("XXX")y=color(green)(-1.25)x+color(red)3`
with a slope of `color(green)(-1.25)` and a `y`-intercept of `color(red)3`
