Find the equation of the tangent to the curve , where is parallel to the line .

Question

Philoid · Accepted Answer

We know that if two straight lines are parallel then their slope

are equal. So, slope of required tangent is also equal to 4.

x = -6 and y = -11

y – b = m(x – a)

y – (-11) = 4(x – (-6))

4x – y + 13 = 0
