2. The slope of a line perpendicular is the negative reciprocal so the slope of the line perpendicular to the given line is 1/3.

3. Use point slope form with the given point to find the equation of the line first before simplifying it to y=mx+b.

Point slope form is y - y1 = m(x-x1) now substitute the point

y-4=1/3(x-2)

4. Now distribute the 1/3: y-4=1/3x - 2/3

Then add 4 to the other side, make 4 into 12/3 to give it a command denominator making it easier to add.

y = 1/3x + 10/3.
