Answer:
f(x) = -2x -3
Step-by-step explanation:
-3 is the point in the y-axis, making it value b
the slope is 1/-2 making the value m = -2
Answer:
it looks like the input will get subtracted by 5
Step-by-step explanation:
Answer:
3 34
Step-by-step explanation:
because because it just is in the first question
Anyway, equation is (x-h)²+(y-k)²=r^2,
(h,k) is center and r is radius
<span>
</span>
since center is (0,0), we get (x-0)²+(y-0)²=r² or simply x²+y²=r²
<span>
</span>
to find r², subsitute the point (-9,0)
<span>
</span>
(-9)²+(0)²=r², 81+0=r², 81=r², 9=r
<span>
</span>
equation is x²+y²=9² or x²+y²=81
