Find the slope: Find the slope m of the line using the slope formula m=x2−x1y2−y1.m=(−2)−(−3)(−4)−(−1)m=−2+3−4+1m=1−3m=−3
Use point-slope form: Use the point-slope form of the equation of a line: y−y1=m(x−x1). Choose one of the points, say (−3,−1), to plug into the equation. y−(−1)=−3(x−(−3))y+1=−3(x+3)
Distribute the slope: Distribute the slope on the right side of the equation. y+1=−3x−9
Subtract to isolate y: Subtract 1 from both sides to get y by itself.y=−3x−9−1y=−3x−10
