My teacher taught us a song for this. It's kind of my favorite thing. It's called the circle song if you ever want to look it up.

is the formula. Therefore:
Answer:
y=6
Step-by-step explanation:
The equation of the line with slope 2 is y=2x+b, b is a constant which should be determined. The line passes via through points (1, 2) and (3,y)
(1, 2): 2=2+b --> b=0
So, the equation of the line is y=2x. Now, when x=3, y=6. So the line y=2x passes through points (1, 2) and (3, 6). (3,y)=(3, 6).
The answer is b, 5x^2 + 24x + 1
Answer:
12
Step-by-step explanation:
The square root of 144 = 12.
12 x 12 = 144
Hope that helps!
Theres information missing in the question. There should be one more pair of coordinates
