Slope = (difference in y coordinate) / (difference in x coordinate) = (17 - 5) / (4 - 2)
= 12/2 = 6

If you mean: y = -2x+17 then the perpendicular slope line is 1/2 or 0.5
Answer:-10/2=-5Solution:The relation between the line slope and it's perpendicular line slope is negative reciprocal, i.e.Slope of the line perpendicular = -1/Slope of the line= -1/(2/10)= -1 x 10/2= -10/2= -5
Point: (2, 17)Slope: 7Equation: y = 2x+13
2. Parallel lines have the same slope.
The slope of the perpendicular to a line has a slope which is the negative reciprocal of the original line's slope.The negative reciprocal of x is -1/xSo in this case, where the slope is -2 the perpendicular line has the slope -1/(-2) or simply 1/2
