#### Answer

slope = 0
y-intercept = 3

#### Work Step by Step

The slope of a line is always equal to the change in y divided by the change in x. Sometimes change can be represented by the Greek letter delta (which looks like a triangle), but it just means the difference between two points.
The slope can be found by picking any two points on the line. I chose (0,3) and (3,3), but any others will work just as well.
$x_{1}=0$ $y_{1}=3$
$x_{2}=3$ $y_{2}=3$
Simply divide the change in y (3-3) by the change in x (0-3):
$m=\frac{y_{1}-y_{2}}{x_{1}-x_{2}}=\frac{3-3}{0-3}=0$.
Since your numerator is 0, your slope is 0.
Your y-intercept is the point where the line crosses the y-axis. This can be found by plugging x=0 into the line equation. However, since we are not given an equation, you can look at the graph and see that when x=0, y=3.
So, the y-intercept =3.
