Q. Complete the point-slope equation of the line through (1,6) (-1,6) and (1,5) (1,5) .\newlineUse exact numbers.\newliney6=y - 6 = \square
  1. Calculate Slope: To find the point-slope form of the equation of a line, we first need to calculate the slope of the line using the two given points (1,6)(-1,6) and (1,5)(1,5). The slope mm is given by the formula m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}, where (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) are the coordinates of the two points.
  2. Substitute Coordinates: Substitute the coordinates of the points into the slope formula: m=561(1)=12=12m = \frac{5 - 6}{1 - (-1)} = \frac{-1}{2} = -\frac{1}{2}.
  3. Apply Point-Slope Form: Now that we have the slope, we can use the point-slope form of the equation of a line, which is yy1=m(xx1)y - y_1 = m(x - x_1), where mm is the slope and (x1,y1)(x_1, y_1) is a point on the line. We can use either of the two points given, but let's use the point (1,6)(-1,6).
  4. Final Equation: Substitute the slope and the coordinates of the point into the point-slope form: y6=(12)(x(1))=(12)(x+1)y - 6 = \left(-\frac{1}{2}\right)(x - (-1)) = \left(-\frac{1}{2}\right)(x + 1).
