Question

Determine the equation of the line that is perpendicular to the given line, through the given point.

y = 3x+4; (9,-7)

Step 1

The required straight line is completely specified by the given geometric conditions; we need to determine its equation (using this information).

Step 2

Two straight lines are perpendicular if and only if theproduct of the slopes is * -1*.

Step 3

Using the above, we determine the ...
