I'm here to help. Those 3 points all lie on the same line. We know this because if we find the slope between any 2 of those points, it is the same. I'll show you: 
. Now another 2 points: 
. The same holds for the first and third points. So we got that out of the way. Now we will pick any one of those points and use the x and y values and our slope to write an equation of that line and then finally solve for the x and y intercepts. I'm going to use the first point (10, 20): 
. We will simplify to get it into y = mx + b form: 
and 
and finally, 
. The y-intercept exists when x = 0, so when x = 0, y = 36. The x-intercept exists when y = 0, so when y = 0, x = 22.5. In summary, y-intercept: (0, 36). x-intercept: (22.5, 0) and you're all done!
Which of the following is the complete solution to the equation? (X-10)(X+8)=0

Answer:

Step-by-step explanation:
To find the circumference, you must first find either the diameter or the radius.
To find the diameter, you can multiply the radius twice.
To find the radius, you can divide the diameter by 2.
Once you have the diameter, you then multiply it by pi, also known as 3.14.
OR
Once you have the radius, you them multiply it by pi, also known as 3.14, and then multiply your product by 2.
