4.0/ 4.0 Points
Question 1 of 254.0/ 4.0 PointsIdentify the slope and the y-intercept of the equation:y = x + 4
A. slope = 0; y-intercept is (0, - 5) B. slope = 0; y-intercept is (- 5, 0) C. slope = 1; y-intercept is (4, 0)D. None of these. E. slope = 1; y-intercept is (0, 4) Feedback: Correct! The slope-intercept equation of a line (y - mx + b) is an easy way to the identify the slope and y-intercept.
