Pi=3.14, So 86 x 3.14= [ 270.04]
52m(-872)=92.28763m
The method would be the power of m with 92=92.28763
The answer is y=2x+5
To get it use point slope by taking two points and solving .
Slope formula
M= y2-y1/x2-x1
With two points
(0,5)(-5,-5)
M= -5-5/-5-0
M= -10/-5
M=2
2 is slope
Now get one of the points
(0,5) And slope to create equation y=mx+b . Now find b
5=2(0)+b
5=b
So now you can put it all together
Y= 2x+5
Down three and over left four so something like (-3, -4) im pretty sure
