The answer should be (C):y=(-3/7)x+3 because:
if you use the slope formula: (Y2-Y1)/(X2-X1) it would look like this:
(0-3)/(7-0) and the slope of the line would be -3/7
then using the slope you just found, plug it into the y=mx+b equation along with one set of coordinates to find b (the y-intercept):
y=mx+b
0=(-3/7)(7)+b
b=3
SO, overall if you put the slope (m) and the y-intercept (b) that you found together, you get the line formula of y=(-3/7)+3
The answer is 2.67 seconds per second when rounded but 2.66666...
By giving just the radius and asking for the arc length of that circle your answer will be without math is 22

But;
Let’s do same math!
Arc length = (()/360)⋅2⋅⋅

In this case angle of arc was not specified so: 360∘
