Answer: 1
1
Explanation:
1
The initial value is also known as the y-intercept, and as you can see on the graph, the y-intercept is 1.
You could also use the formula
y=mx+b, b is the y-intercept, m is slope, y and x are coordinates.
We see one of the coordinates in (-2,0) so x=-2 and y=0
The slope, or rate of change, is 1/2, so m=1/2
Now plug the numbers into the formula:
0=1/2(-2)+b
0=-1+b
1=b
