<h2>Hello!</h2>
The answer is:
The correct option is the first option:
To write the equation of the line in slope-interception form we need to extract all the information that we need from the graphic.
We must remember that the slope-interception form of the lines is:
Where,
y, is the function
m, is the slope of the line
x, is the variable
b, is the y-axis intercept
We can find the slope using the following formula:
Which is for this case:
As we can see from the graphic, the line is decresing, so the sign of the slope "m" will be negative, so:
We can find the value of "b" seeing where the line intercepts the y-axis.
As we can see it intercept the y-axis at:
Then, now that we already know the value of "m" and "b", we can write the equation of the line:
So, the correct option is the first option:
Have a nice day!
Answer:
82
Step-by-step explanation:
We are given that a graph which shows the number of beads used for varying cord lengths.
The graph
We have to find the number of beads that she can used for cord length 32 in.
Substitute the value x=32
Then, we get
After round to unit place then, we get
y=82
Hence, the best estimate she can used for number of beads =82
Answer: 82
