Answer:
slope=4/5
y-intercept = -3
Step-by-step explanation:
first we need to rewrite the expression to

were b is the y-intercept and m the slope

so there we have it

I believe the answer your looking for is B.. good luck my friend!
We have the following function that is a
quadratic function:
So the graph of this function is shown in the figure below. This is a <em>parabola</em> as you can see. The roots of this functions, that is, the x-intercepts are:

As you can see in the figure. This function decreases from

and increases from

Finally, another thing we can see from the graph is that the vertex is the point:
