Question

How do you write an equation of a line with (-2,3); m=-1?

Answer 1

`y=-x+1`

Explanation:

Slope-intercept form of a line: `y=mx+b`, where m is the slope and b is the y-intercept

Put -1 in for m:

`y=-x+b`

To solve for b, put in the point `(-2, 3)`.

`3=-(-2)+b`

`3=2+b`

`b=1`

The equation is `y=-x+1`
