If
X = 2 4 6 8
y = 1 -2 -5 -8
What is the slope
I know that slope = vertical change over horizontal change and rise over run
so, did you check the values?
x-change = +2
y-change = -3
slope = -3/2
thank you
To determine the slope, we need to calculate the vertical change (rise) and the horizontal change (run) between two points on the line. In this case, we can use the values of X and y given:
1. Choose two points from the given values of X and y. For convenience, let's choose the first and second points: (2, 1) and (4, -2).
2. Calculate the vertical change (rise) by subtracting the y-values of the two points: -2 - 1 = -3.
3. Calculate the horizontal change (run) by subtracting the x-values of the two points: 4 - 2 = 2.
4. Now divide the vertical change (rise) by the horizontal change (run) to get the slope: -3 / 2 = -1.5.
Therefore, the slope of the line is -1.5.
