Answer:
3/4
Step-by-step explanation:
To find the slope using a line on a graph, calculate the difference between two points. To do so, use the formula y2 - y1/x2 - x1.
Two points on this line are (0, -1) and (4, 2). This means:
y2 = 2
y1 = -1
x2 = 4
x1 = 0
Plugging those values in, we get:
2 - (-1)/4 - 0
Evaluating 2 - (-1) and 4 - 0, we get 3/4. Therefore, the slope is 3/4.
Answer:
-3 or decreasing by 3
Step-by-step explanation:
To find the average change, you only care about the first and last point which would be (3,17) and (8,2)
the overall change during that time is 2-17=-15 (for the f(x) side )
the overall change during that time is 8-3=5(for the x side)
all we have to do is -15/5=-3
therefore the average rate of change is -3
Answer:
To make this easier, first draw or imagine a vertical line at x=2
Find where the vertical line and the graph intersects.
Draw or imagine that point of intersection.
Now, draw or imagine a horizontal line that goes through the point of intersection.
That horizontal line tells us the the value of the function by passing through that mark that says "-2"
The function's value at x=2 is -2.
