between points (x0, y0) and (x1, y1):
slope = change_in_y/change_in_x
→ slope = (y1 - y0)/(x1 - x0)
→ slope = (3 - 0)/(1 - 2) = 3/(-1) = -3

Points: (-2.5, -0.5) and (4.5, -1) Slope: -1/14 Equation: y = -1/14x-19/28 in slope intercept form
The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.
m=1/0 The m(slope) is 1/0 because it is rise over run. The line is "rising" but not "running".
1st find the midpoint -- (4, 1/2) Now slope -- 1/2 divided by 4 = 1/8 y-intercept = 0 (origin) y = (1/8)x <--- answer
Slope = (change_in_y) / (change_in_x) = (4 - 3) / (5 - 0) = 1/5 = 0.2
