Answer: 169
Step-by-step explanation:
52 divided by 4 is 13 so 13 times 13 is 169
You can tell if a graph represents a proportional relationship by identifying the y-intercept, or the point of the line that crosses the y-axis.
If the y-intercept is 0, then the relationship is proportional. This is called a direct relationship.
If the y-intercept is anything other than 0, then the relationship is not proportional. This is called an indirect relationship.
I hope this helps!
The answer for your question is (1/2) and alternate form is 0.5 and 2^-1
Answer:

Step-by-step explanation:
Use the slope-intercept form:

m is the slope and b is the y-intercept. Looking at the graph, you can find the y-intercept. The y-intercept is the point where x equals 0:


To find the slope, take any two points from the line:

Use the slope formula for when you have two points:

The rise over run is the change in the y-axis over the change of the x-axis. Insert the appropriate values:


Simplify parentheses (two negatives makes a positive):


Simplify (two negatives make a positive):

The slope is
and the y-intercept is
. Insert these into the equation:

Finito.
I am confused by this question. But I will try to answer. Is it Exponential Decay?
