    At what point does the normal to y=-5-1x+3x^2 at (1, -3 ) intersect the parabola a second time? Answer: Note: You should enter a cartesian coordinate. The normal line is perpendicular to the tangent line. If two lines are perpendicular their slopes are

    Find the slope of any line parallel to the line through points (17, 4) and (5, 8). the slope of these is: 8-4 4 1 ----- = --- = --- 17-5 12 3 is 1/3 the correct answer? No you started with the y of the second point, so you have to start with the x of the

    1. Which line is the flattest (or is less steep)? Why? a.y = 5x -6 b.y = 5x + 6 c.y = x - 3 d.y = x + 3 I think this question has been aswered a couple times, but I'll try again. The slope is given by the number before the x varible. The first two choices

    I am looking for a perpendicular line. I'd appreciate ir if you could tell me if I'm on the right track. I am given y=-5x + 4 and know that a perpendicular line passes through (3,5). I think the slope of this line would be 1/5 so it would go up (rise) 1,
