2. The equation 3x + 4y + 5 = 0 and 4x – 3y + 7 = 0 represent perpendicularlines.T About the author Gabriella
Slope of line = -(Coefficient of x)/(Coefficient of y) Slope of first line = m1 = -3/4 Slope of second line = m2 = 4/3 m1*m2 = -1 Therefore the lines are perpendicular Please mark as brainliest answer Reply
Slope of line = -(Coefficient of x)/(Coefficient of y)
Slope of first line = m1 = -3/4
Slope of second line = m2 = 4/3
m1*m2 = -1
Therefore the lines are perpendicular
