?
Which of the following is the graph of the equation
Since the intercepts are shown on each graph, we need to find the intercepts of 
.
To find the 
-intercept, set 
and solve for :
Therefore the 
-intercept is 
.
To find the 
-intercept, set 
and solve for :
Thus the 
-intercept is 
.
The correct choice is the line that passes through these two points.

Which of the following graphs best represents the following function?
Which of the following graphs best represents the following function?
This equation describes a straight line with a slope of 
and a y-intercept of 
. We know this by comparing the given equation to the formula for a line in slope-intercept form.
The graph below is the answer, as it depicts a straight line with a positive slope and a negative y-intercept.
This equation describes a straight line with a slope of

Which of the following choices is an accurate visual description of the graph of
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
