Q. Complete the equation of the line through (−1,6) and (7,−2).Use exact numbers.y=□
Calculate the slope: To find the equation of a line, we need to determine the slopem of the line using the formula m=(x2−x1)(y2−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)m=(8)(−8)m=−1
Write the 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))y−6=−1(x+1)
Simplify the equation: Next, we simplify the equation by distributing the slope −1 across the terms in the parentheses.y−6=−1×x−1×1y−6=−x−1
Convert to slope-intercept form: To write the equation in slope-intercept formy=mx+b, we need to solve for y. y=−x−1+6 y=−x+5
