Question #85dee

Answer 1

The slope is `m=-5` and the `y`-intercept is `(0,7)`.

Explanation:

Given `y=mx+b` the slope of the line is `m` and the `y`-intercept is `(0,b)`.

We have `y+5x=7` which we can rearrange to `y=-5x+7`.

The slope is `m=-5` and the `y`-intercept is `(0,7)`.

Answer 2

`"slope "=-5," y-intercept "=7`

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"`

`"rearrange "y+5x=7" into this form"`

`"subtract 5x from both sides"`

`ycancel(+5x)cancel(-5x)=7-5x`

`rArry=-5x+7larrcolor(blue)"in slope-intercept form"`

`rArr"slope "=-5" and y-intercept "=7`

Answer 3

so lets compare it to the general equation, `y=mx+c`....

`y+5x=7`
`y=-5x+7`

so then, `m=-5` and `c=7`

p.s. c is the y intercept.:)
