The slope of this line is ___.?
9. Given points A(-4, 5), B(2, 3), C(0, 4) and D(5, 0), decide if AB and CD are The distance from (-4,5) to (2,3) is 6.3246 on x +3y=11 or y = -0.3333x +3.6667 The distance from (0,4) to (5,0) is 6.4031 on 4x +5y=20 or y = -0.8x +4 slopes are different, do not multiply to -1 so they are neither parallel nor perpendicular
Slope of the Line and Midpoint?
What is the slope of the line joining (2,-3) and the midpoint of the line segment joining (0,4) and (5,-2)? These were previous problems form the Math Exit Exam Reviewer..Please anyone help me for my review.. I will automatically rate 5 stars for the best answer...Thank you very much! :)
At what value(s) of x in the interval [0,2] is the slope of the line tangent to f(x) = x^3 - 3x^2...?
(0, f(0)) = (0, 0) (2, f(2)) = (2, -4) The slope can be found using the equation m = (y2 - y1)/(x2 - x1): m = -4/2 = -2 Differentiate f(x) to find the gradient formula: f'(x) = 3x^2 - 6x To make the lines parallel, let f'(x) = -2: 3x^2 - 6x = -2 3x^2 - 6x + 2 = 0 Use the quadratic formula to solve for x: x = [6 ±√6^2 - (4 x 3 x 2)] / 6 x ≈ 0.423, 1.577 (2 d.p.) ∴ The answer is E.
