Question

How do you find the slope given `4x + y = 7`?

Answer 1

`"slope "=-4`

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 "4x+y=7" into this form"`

`"subtract "4x" from both sides"`

`rArry=-4x+7larrcolor(blue)"in slope-intercept form"`

`"with slope "=-4`
