If the line is tangent at (3, 4), what is the value of m? Express your answer as a common fraction. Spoiler:This one requires some geometry experience. You have to know that a line tangent to a circle is perpendicular to the line from the point of intersection to the center. So, first, find out the slope of the line from the center to the point of intersection. (difference in rise)/(difference in run)= ...
