Find the equation of the straight line passing through the point (3,5)

marysya [2.9K]

Answer:

Step-by-step explanation:

y = 3x + 2

Slope m = 3

slope of the line perpendicular to this line = -3

Point (3,5)

y- y1 = m(x-x1)

y - 5 = -3(x-3)

y - 5 = -3*x-3 * -3

y - 5 = -3x + 9

y = -3x + 9 +5

y = -3x + 14
