A circle is 360 degrees. When you have 7/10, you would multiply it by 36. This is because in the denominator, 10x36=360. 7x36? 252.
So it would be 252 degrees.
I believe it would be about 1.57
The linear rule should look like this y=a*x+b
As the function graph goes through the (0,0) point, the equation 0=a*0+b <=> b=0 must be true.
Now we only need to find a, using one of the points given. With (-4, 16):
16=-4*a <=> a=16/-4 <=> a= -4
So the rule looks the following way:
f(x)= -4*x
The answer was A but i am found
1.557, -11.557
and hope that helps you
