Q. Halle la ecuación de la recta que es perpendicular a la recta y=2x+1 y pasa por el punto (−2,7)
Identify slope: Identify the slope of the given line y=2x+1. The slope (m) is 2.
Find perpendicular slope: Find the slope of the perpendicular line. The slope of the perpendicular line is the negative reciprocal of 2, which is −21.
Use point-slope form: Use the point-slope form of the equation of a line, y−y1=m(x−x1), where (x1,y1) is the point (−2,7) and m is −21.
Substitute point and slope: Substitute the point (−2,7) and the slope −21 into the point-slope form: y−7=−21(x+2).
Simplify equation: Simplify the equation: y−7=−21x−1.
Convert to slope-intercept form: Add 7 to both sides to get the equation in slope-intercept form: y=−21x+6.
