The slope of this secant line can be computed since we know two points on the line. (click "triangle"). Move the slider to 0 and observe how the secant lines approaches a line that just touches the ...

If y = 4x + 3 is parallel to a tangent to the parabola y 2 = 12x, then its distance from the normal parallel to the given line is. Solution 4: We have equation of line, y = 4x + 3. So, slope of ...
