Question

Write an equation in slope-intercept form for a line with a slope of -1 through the point (3, -1)

Answer 1

y= -x+2

Explanation:

y=mx+b is slope intercept form

m is slope

b is y intercept

we know m is equal to -1 so we can fill it in

y=-1x+b

to find b we fill in the given coordinates of (3,-1)

-1= -1(3)+b

-1= -3+b

+3. +3

2=b

now that we know b we fill it in

y=-1x+2

simplify

y= -x+2
