Q. ad the equation of the line perpendicular to y=9 through the point (−6,−2)
Find Slope of Line: Find the slope of the line y=9. Since it's a horizontal line, the slope is 0.
Perpendicular Line Slope: Determine the slope of the line perpendicular to y=9. Perpendicular lines have slopes that are negative reciprocals. The negative reciprocal of 0 is undefined, which means the perpendicular line is vertical.
Vertical Line Equation: Write the equation of the vertical line passing through (−6,−2).A vertical line has the form x=a, where a is the x-coordinate of the point it passes through.
Substitute X-coordinate: Substitute the x-coordinate of the point into the equation.x=−6 is the equation of the vertical line.
Check Point on Line: Check if the line passes through the given point (−6,−2).Substitute −6 for x and see if the y-coordinate is −2.Since it's a vertical line, all points on the line have x=−6, so it passes through (−6,−2).
