The formula to get the circumference of a circle is $C=2*\pi * r$ but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this $C=d*\pi$ .

We can then input the value and we get that $C=1*\pi$ which then just narrows down to $C=3.142$ .

Hope this helps! Let me know if you have any questions

Answer:

see the attachment

Step-by-step explanation:

The x- and y-intercepts are easily found:

X-intercept

Set y = 0 and divide by the coefficient of x.

-x +0 = 8

x = -8

Y-intercept

Set x = 0 and divide by the coefficient of y.

0 -2y = 8

y = -4

Now, we have two points on the graph: (-8, 0) and (0, -4). A third point can be one that is halfway between these: (-4, -2). The graph is attached.
