Question:medium
A straight line parallel to the line \( 2x - y + 5 = 0 \) is also a tangent to the curve \( y^2 = 4x + 5 \). Then the point of contact is:
A straight line parallel to the line \( 2x - y + 5 = 0 \) is also a tangent to the curve \( y^2 = 4x + 5 \). Then the point of contact is:
Show Hint
The slope of a curve at any point $(x, y)$ is simply the derivative $dy/dx$. Parallel = Same Slope; Perpendicular = Negative Reciprocal Slope.
