Question

What is the equation of the line that passes through the point (3, 0) and has a slope
of -1?

Answer 1

y= -x+3

Explanation:

the equation of line through the point (x1, y1) and has a slope m is

(y-y1)= m(x-x1)

Here (x1, y1)=(3,0)

and slope m=-1

since

the equation of line

y-0=-1(x-3)

y= -x+3

therefore the equation of line is

y= -x+3

Answer 2

y = -x + 3

Explanation:

Plug into point slope form:

y - 0 = -1(x - 3)

y = -x + 3
