Full solution

Q. Make and equation (3,1)(2,4)(-3,-1)(-2,-4)
  1. Find the slope: Find the slope mm of the line using the slope formula m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}.m=(4)(1)(2)(3)m = \frac{(-4) - (-1)}{(-2) - (-3)}m=4+12+3m = \frac{-4 + 1}{-2 + 3}m=31m = \frac{-3}{1}m=3m = -3
  2. Use point-slope form: Use the point-slope form of the equation of a line: yy1=m(xx1)y - y_1 = m(x - x_1). Choose one of the points, say (3,1)(-3, -1), to plug into the equation. y(1)=3(x(3))y - (-1) = -3(x - (-3)) y+1=3(x+3)y + 1 = -3(x + 3)
  3. Distribute the slope: Distribute the slope on the right side of the equation. \newliney+1=3x9y + 1 = -3x - 9
  4. Subtract to isolate yy: Subtract 11 from both sides to get yy by itself.\newliney=3x91y = -3x - 9 - 1\newliney=3x10y = -3x - 10
