Question

Which line is perpendicular to the line y= -1/3 x - 2 and passes through the point (1,4)?

Answer 1

y = 3x + 1

Explanation:

y= -1/3x

perpendicular so y = 3x + b

the line goes through (1,4), so substitute to find the value b , which is where the line intersects with the y axis.

4 = 3*1 +b

so b = 1

y = 3x + 1
