For every change in x, y changes 2/pi.
In order to find this we first need to evaluate the expression at the intervals.
x = 0
f(x) = 1 + sinx
f(0) = 1 + sin0
f(0) = 1 + 0
f(0) = 0
x = pi/2
f(x) = 1 + sinx
f(pi/2) = 1 + sin(pi/2)
f(pi/2) = 1 + 1
f(pi/2) = 2
So the total change in y is 1. So we divide that by how much x has changed in that interval to find the average rate of change.
1 / (pi/2) = 2/pi

The answer to the question
Answer:
y = x + 3 or y = 1x + 3
Step-by-step explanation:
Since we're just going to find the equation (assuming it's slope-intercept form, which is <em>y = mx + b</em>), our jobs will be relatively simple!
Let's start with the first step and identify the y-intercept, which is the easiest step.
That will be (0,3), as the line intercepts the y-axis there.
Next, let's find the slope of the line using or . Just be careful when using that you correctly identify the scale the axis' are using.
For now, I'll use . Let's pick two points... (0,3) and (1,4).
—> =
This will be our slope, 1.
We now have our answer, y = 1x + 3.
Hope that helped!
