Which of the following choices is an accurate visual description of the graph of
Though this is a question about a graph, we don't actually have to graph this equation to get a visual idea of its behavior. We just need to put it into slope-intercept form. First, we subtract 
from both sides to get
Simplified, this equation becomes
Remember, this is in 
form, where the slope is represented by 
. Therefore, the slope is negative. The y-intercept is represented by 
, which is 
in this case. So, the line has a negative slope and crosses the 
-axis at 
.

Which equation matches the graph of the line shown?
Which equation matches the graph of the line shown?
An equation of a line is made of two parts: a slope and a y-intercept.
The y-intercept is where the function crosses the y-axis which in this problem it is 0.
The slope is determined by the rise of the function over the run which is 
, so the function is moving up one and over one.
Therefore your equation is:
, which is simply

Which image depicts the point
The first number, 
indicates how far the point is positioned to the left or right of the origin. Because the number is negative, the point is three units to the LEFT of the origin. The second number indicates how far the point is postioned up or down from the origin. Because the number is positive, the point is located four units above the origin.

To answer this question, we will have to manipulate the distance formula:
To get rid of the square root, we can square both sides:
and plug in the information given in the question.
At this point we can simply plug in the possible values to determine which combination of coordinates will make the equation above true.
Thus the correct coordinate is,

To graph these points we just need to remember that the first number is the x value and the second number is the y value. For (A) we have (1,3). So we move one tick over on the positive x-axis. Then from there we move up to the third tick on the y axis:
If the value is negative we must move in the other direction. So, for all 4 points,

What are the coordinates of the point on the given graph?
What are the coordinates of the point on the given graph?
When trying to determine coordinates of a point you need to look at the value of x first (how many units left or right the point is, then the y-value (how many up or down it is).
When you look at this point you see that it is moved right 2 units and up 1.
So your coordinates are:

Which equation best represents the following graph?
Which equation best represents the following graph?
We have the following answer choices.
The first equation is a cubic function, which produces a function similar to the graph. The second equation is quadratic and thus, a parabola. The graph does not look like a prabola, so the 2nd equation will be incorrect. The third equation describes a line, but the graph is not linear; the third equation is incorrect. The fourth equation is incorrect because it is an exponential, and the graph is not an exponential. So that leaves the first equation as the best possible choice.

Which graph depicts a function?
A function may only have one y-value for each x-value.
The vertical line test can be used to identify the function. If at any point on the graph, a straight vertical line intersects the curve at more than one point, the curve is not a function.
