Slope formula
y2-y1/x2-x1
5-3/2-4
2/-2
-1 = slope
y=-1x+b
5=-1(2)+b
5=-2+b
b=7
Your answer:
y= -1x + 7
For this case, we must find an expression equivalent to:
By definition of power properties we have:
Rewriting the previous expression we have:
The "-" are canceled and we take into account that:
So:
According to one of the properties of powers of the same base, we must put the same base and add the exponents:
Answer:
Option B
Do you think the answer is C.147?
