Write an equation of the line that passes through (1, 2) and is perpendicular to the line y = 1/3x+4. An equation of the perpendicular line is
y = ?

Answer 1

Answer:

I'm not sure but I believe its y=-3x+5

Step-by-step explanation:

You start off by finding slope which is -1/m. So 1/1/3=-3. From here you plug in the variables (1,2) and solving. The equation becomes y=-3x+b. From here plug in x and y. So, 2=-3+b. From here add 3 to both sides and you get 5=b. Then just put it together. y= -3x+5
