Question

. A perpendicular from the origin meets a line at (4, -5), find the equation of the (a) perpendicular (b) line​

Answer 1

Answer:

y = ⅘x - 41/5

Step-by-step explanation:

slope of the line from the origin = -5/4

slope of any perpendicular to the line = ⅘

equation of the line from the origin:

y = -(5/4)x

perpendicular to the line that passes through (4,-5):

y+5 = ⅘(x-4)

y = ⅘x - 41/5
