Find the equation of a line that is perpendicular to line g that contains (P. Q).

3x - y = 3P - Q

Step-by-step explanation:

Given line has slope rise/run = - 1/3.

For the perpendicular line slope = 3.

y = 3x + b

Point (P, Q)

Q = 3P + b

b = Q - 3P

y = 3x + Q - 3P

3x - y = 3P - Q

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
