Question

How do you find the slope given y=2x+9?

Answer 1

slope `=2`

Explanation:

Given equation

`y=2x+9`

Comparing the above equation with the standard form of slope-intercept form `y=mx+c` we get

Slope: `m=2`

y-intercept: `c=9`

Answer 2

`"slope "=2`

Explanation:

`"the equation of a line in "color(blue)"slope-intercept form"` is.

`•color(white)(x)y=mx+b`

`"where m is the slope and b the y-intercept"`

`y=2x+9" is in this form"`

`"with slope "=2" and y-intercept "=9`

Answer 3

See below:

Explanation:

The key realization is that our equation is of the form

`y=mx+b`, commonly called slope-intercept form, where `m` is the slope and `b` is the `y`-intercept.

We see that our coefficient on `x` is `2`- this is our slope.

We also see that our constant is `9`- this is our `y`-intercept.

Hope this helps!
