Answer:
The slope would be 1 over -2 or -0.5
Step-by-step explanation:
Rise (change in y) over run (change in x)
Point A (-2, 2)
Point B (0, 1)
2 - 1
-------- = -0.5
-2 - 0
The slope of the given line can be found by finding the ratio of difference in y ordinate and difference in x abscissa.
The slope of given line is calculated as -1/2 = -0.5
Given that:
- The first point's coordinate = (-2,2)
- The second point's coordinate = (0,1)
- The points are joined by a line.
To find:
Slope of aforementioned straight line.
Calculation of slope:
Slope is ratio of rise vs run.
The coordinate is expressed as (x abscissa, y ordinate).
The "run" is calculated as difference in x abscissa of two points on a line.
Thus:
run = -2 - 0 = -2
The "rise" is calculated as how much y ordinate rise on that run, and thus its a difference of y ordinates of those two points:
rise = 2 - 1 = 1
Thus, the slope is:
[tex]slope = \dfrac{rise}{run } = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{1}{-2} = -\dfrac{1}{2}[/tex]
Thus, slope of given line is -1/2.
