By using the graph (see attachment), the coordinates of the y-intercept of the parabola is (0, 7).
<h3>What is a graph?</h3>
A graph can be defined as a type of chart that's commonly used to graphically represent data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
In Mathematics, the y-intercept of any graph (parabola) occurs at the point where the value of "x" is equal to zero (0).
By critically observing the graph (see attachment), the coordinates of the y-intercept of the parabola is given by:
y-intercept = (0, 7).

Answer:
the answer is 45.
Step-by-step explanation:
45 + 23 = 68.
We must find the slope of the graph first, we can do this by finding two perfect points and inputting those points into the formula y2 - y1/x2 - x1
Perfect point #1: (0,1)
Perfect point #2: (2,5)
As mentioned above, input these numbers into our formula.
5-1 = 4
2 - 0 = 2
4/2 = 2
So, the slope of the graph is 2.
Now, we must find the y-intercept which can be found based on where the line intersects with the y-axis. As we can see, the line intersects at (0,1) therefore the y-intercept of the graph is 1.
We now form a linear equation:
y = 2x + 1
However, since this is linear equality graph we will replace the equal sign with an inequality symbol. The inequality symbol we can use is based on the direction of the shaded area. If shaded up, we use the "greater than symbol", if down then we use the "less than symbol".
The line also matters, if the line is dotted we use the normal inequality symbol, but if it is straight then we use one of the "equal to" inequality symbols.
As for our graph, we have a dotted line with the shaded area upwards. Therefore, we will be using the greater than symbol and not a "equal to" symbol.
So, our answer would be y > 2x + 1
Answer:
Answer D
Step-by-step explanation:
The answer here is D since all of the other ones have at least one option that is perpendicular to segment EF.
