Question

Standard form of the equation that goes through (3, -1) with a slope of -1, please!

Answer 1

x+y=2

Explanation:

Standard Form: ax+by=c

For most convenience start with slope-intercept form: y=mx+b

1. -1 = -1(3)+b - solve for b

b=2

y= -1x+2 (slope-intercept form)

2. Now convert to standard form

Add 1x to both sides:

1x+y=2
