To find slope:
(y1 - y2) / (x1 - x2)
(0-3)/(-4-0)
Slope is 3/4
So the equation is
y=3/4x + 3
So it would be
40-.07(40)=b
B=37.2 dollars
Move all the logarithms on the left hand side, and all the constants on the other:

Use the rule of logarithms

To rewrite the equation as

Evaluate 2 to the power of each side:

Multiply both sides by 2x:

Using PEMDAS
(Parenthesis)(Exponents)(Multiplication/Division)(Addition/Subtration)
So:


Answer:
2, -3
Step-by-step explanation:
I think this is right.
Maybe just wait till someone else answers just to makae sure this is exactly the right answer.
