The answer is B) multiply 3 by 3. With that 2 on top, that doesn't mean 3 times 2, that means multiply 3 by itself, however many times the number says, if that makes sense. So if there's a 2 above the 3, then that would be 3*3. If it was a 5 instead of a two, that would mean 3*3*3*3*3. Not 3*5.
Estimation :
20/0.05 = 400
y=-2x+5 since b is the y intercept so it is 5 and it is a negative slope so 2/-1 is -2
