Q. Complete the equation of the line through (−1,6) and (7,−2).Use exact numbers.y=□
Calculate Slope: To find the equation of a line, we need to determine the slopem of the line using the formula m=x2−x1y2−y1, where (x1,y1) and (x2,y2) are the coordinates of the two points the line passes through.Let's calculate the slope using the points (−1,6) and (7,−2).m=7−(−1)−2−6=8−8=−1
Use 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.Let's use the point (−1,6) and the slope −1 to write the equation.y−6=−1(x−(−1))
Simplify Equation: Simplify the equation by distributing the slope −1 into the parentheses.y−6=−1(x+1)y−6=−1x−1
Isolate y: To write the equation in slope-intercept formy=mx+b, we need to isolate y on one side of the equation.Add 6 to both sides of the equation to isolate y.y=−1x−1+6y=−1x+5
Final Equation: The equation of the line in slope-intercept form is now y=−1x+5, which can also be written as y=−x+5. This is the final answer in standard form with a leading coefficient of 1 for x.
