Find the equation of a line passing through (−2, 3) and having a slope of −1.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → \(x+y=1\)
A line through the point \((x_1,y_1)\) with slope \(m\) has the point-slope form \(y-y_1=m(x-x_1)\).
\(y-3=-1\,(x+2)\)
\(y-3=-x-2\)
\(x+y=1\)
