Answer:
The Y intercept would be 1. The slope would be 2.
Step-by-step explanation:
The Y intercept is where a line intercepts, or crosses the Y axis. As you can see in the graph, the line crosses the Y axis at point 1.
To find slope here, you can do the rise divided by the run.
To find this, choose two points. We can use point (0, 1) and point (1, 3)
Next, find the rise, or the vertical distance between the two points. In this case, it would be 2.
Then, find the run, or the horizontal distance between the two points. In this case, it would be 1.
Finally, divide the rise by the run, and create the fraction rise over run, or in this case 2/1.
The expression for the width of a rectangle that is 6 centimeters and is (6x 18) square centimeters would be:
18 centimeters
First, let

be a point in our parabola. Since we know that the focus of our parabola is the point (0,8), we are going to use the distance formula to find the distance between the two points:

Next, we are going to find the distance between the directrix and the point in our parabola. Remember that the distance between a point (x,y) of a parabola and its directrix,

, is:

. Since our directrix is y=-8, the distance to our point will be:


Now, we are going to equate those two distances, and square them to get rid of the square root and the absolute value:



Finally, we can expand and solve for

:




We can conclude that t<span>he standard form of the equation of the parabola with a focus at (0, 8) and a directrix at y = -8 is </span>
