Points: (-1, 8) and (5, -4) and the slope works out as -2
let (2,-5) be P1 and (-1,-8) be P2 Slope is -5+8/2+1=3/3=1
slope = change_in_y/change_in_x = (-1 - 2)/(8 - 5) = -3/3 = -1
If you mean points of (0, 4) and (-8, -1) then the slope is 5/8
To find the slope between two points: slope = change_in_y/change_in_x Thus for the points (4, 5) and (6, 8), the slope between them is given by: slope = (8-5)/(6-4) = 3/2 = 1½ = 1.5
If you mean points of (5, 1) and (2, -7) then the slope works out as 8/3
I assume you mean,8X - 5Y = 1- 5Y = - 8X + 1Y = (8/5)X - 5==========m(slope) = 8/5
If you mean points of: (5, 4) and (0, 3) then the slope is 1/5
(4 - 8) / (9 - 5) = -1 or -1/1
If you mean points of: (-1, 8) and (5, -4) then the slope is -2
To solve this, use the slope formula. the slope formula is m = (y2 - y1) / (x2 - x1) Therefore, m = ( -3 - 5)/ (1-2) If you solve this, you will get 8. So the slope of the line is 8.
First find the slope of the given line . 5x + 8y =17 Put this into the 'y = mx + c '. form. Hence 8y = -5x + 17 y =(-5/8)x +17/8 '-5/8' is the slope of the given line. To find the perpendicular slope use the equation mm' = -1 Hence substituting (-5/8)m' = -1 m' = (-1)(-8/5) (Note the inversion of the numbers) m' = 8/5 (Note the double negative multiplies out to a positive), = 1 3/5 = 1.6 is the slope of the perpendicular line.
