This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Consider the point and line below. Point Line (-7, 1) x + y = 8 Exercise (a) Write nequation of the line through the point parallel to the given line. Click here to begin! Exercise (b) Write an equation of the line through the point perpendicular to the given line. Step 1 Two distinct non-vertical lines are perpendicular when their slopes are negative reciprocals of each other. The slope of the required line is equal to the negative reciprocal of the slope of the line x + y = 8 which was found to be -1 In part (a). The negative reciprocal of -1 Ist m=- Step 2 The required line passes through (-7, 1). Substitute the values (x₂, ₁) = (-7, 1) and m = 1 Into the point-slope form of an equation. Y - Y₁ = m(x - x₂) Submit Skip (you cannot come back)
