Free Equation of a line given Points Calculator - find the equation of a line given two points step-by-step

Equation of Tangent line is: ( x – x 1) = m ( y – y 1) ( x – ( − 4)) = ( − 1) ( y – 2) x + 4 = − y + 2 y + x – 2 + 4 = 0 y + x + 2 = 0 When using slope of tangent line calculator, the slope intercepts

Read the problem to discover the coordinates of the point for which you're finding the tangent line. Enter the x-coordinate of this point into f'(x). The output is the slope of the
