Question

How do you write the equation of a line given (-3,5), m= -1?

Answer 1

`y=-x+2`

Explanation:

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

`•color(white)(x)y=mx+b`

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

`"here "m=-1`

`rArry=-x+blarrcolor(blue)"is the partial equation"`

`"to find b substitute "(-3,5)" into the partial equation"`

`5=3+brArrb=5-3=2`

`rArry=-x+2larrcolor(red)"in slope-intercept form"`
