To graph the equation of the line, find the x-intercept and the y-intercept of the function
we have

we know that
The x-intercept is the value of x when the value of y is equal to zero
The y-intercept is the value of y when the value of x is equal to zero
Step 1
<u>Find the x-intercept</u>
For 



the x-intercept is the point 
Step 2
<u>Find the y-intercept</u>
For


the y-intercept is the point 
Step 3
Graph the points and draw the line
see the attached figure
therefore
the answer in the attached figure
Answer:
66 cm
Step-by-step explanation:
Let's define the circumference first.
It is the boundary of any curved geometric figure specially circle.
We are given the diameter of the circle in the diagram
The diameter is:
d = 21 cm
to find the circumference, we have to find the radius of the circle first.
As radius is half of diameter
d = r/2
= 21/2
= 10.5 cm
The formula for circumference is:

The circumference is 66 cm ..
