In this question we will write the equation of a tangent line using the point- slope form of a line shown below. The formula for a line with slope m that passes through (a, b) is, y = m (x - a) +b. Determine the equation for the line tangent to the function f (x) = x - 1 when x = 2. Then answerthe following questions. What is the slope of the tangent line? What is the y-coordinate of the vertical intercept of the tangent line
