Find the slope of the following graphs.
X, -1, 0, 1 ,2
Y, 4, 2, 0, -2
A. 1/2
B. 2
C. -2
D. -1/2
Is the answer B?
Thank you
Nope. How does y change when x increases by 1?
I don't understand how to do this. I didn't know if it was A or B.
(Y2-Y1) / (X2-X1)
for example
(-2-4)/(2 - -1) = -6/3
ok then then the answer would be D right?
To find the slope of a graph, you need to calculate the difference in the y-coordinates (vertical change) divided by the difference in the x-coordinates (horizontal change) between two points on the graph. Let's take points (0,2) and (1,0) on the graph.
The difference in the y-coordinates is y2 - y1 = 0 - 2 = -2.
The difference in the x-coordinates is x2 - x1 = 1 - 0 = 1.
So, the slope is -2/1 = -2.
Now, compare the obtained slope of -2 with the given options:
A. 1/2
B. 2
C. -2
D. -1/2
The answer is not B, as the slope is -2, not 2. Therefore, the correct answer is C. -2.
