Q. Complete the point-slope equation of the line through (−1,6) and (1,5).Use exact numbers.y−6=□
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) and (1,5). The slope m is given by the formula m=x2−x1y2−y1, where (x1,y1) and (x2,y2) are the coordinates of the two points.
Substitute Coordinates: Substitute the coordinates of the points into the slope formula: m=1−(−1)5−6=2−1=−21.
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 y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line. We can use either of the two points given, but let's use the point (−1,6).
Final Equation: Substitute the slope and the coordinates of the point into the point-slope form: y−6=(−21)(x−(−1))=(−21)(x+1).
