Question

What is an equation of the line that passes through the point (3,-1) and is perpendicular to the equation y=-3x+2

Answer 1

If it is perpendicular then the slope of it will be:


`-3 * x = -1\\\\x = (1)/(3)`

y = 1/3 x + b

-1 = (1/3)(3) + b

-1 = 1 + b

b = -2

The equation is:


`y = (1)/(3)x - 2`
