What’s the answer

Question

Which of the following is an equation of the line that is perpendicular to the line y=-1/3 x + 8 in the standard (x,y) coordinate plane?

Answer 1

To do this problem we are going to need to know the coordinates (x,y) of a point that the line passes through. Because the lines are perpendicular, the slope of the second line will be the negative reciprocal of the slope of the first line. In an equation in y=mx+b form, m is the slope.
