because anything divided by 1 is itself, and a fraction is just the numberator divided by the denominator.
Answer:
y = 4/3x - 12
Step-by-step explanation:
To find the slope of the line, we do (y2 - y1) / (x2 - x1)
If we put in the values, we'll get
(-4 - -8) / (6 - 3)
Simplify and get
(-4 + 8) / 3
4 / 3
Your slope is now 4/3, so you can put it into your equation y = mx + b
y = 4/3x + b
To find b, we can plug in the values from one of your points. Lets use (3, -8)
-8 = 4/3 * 3 + b
Now solve the equation
-8 = 4 + b
-12 = b
Now that you have b, your equation is complete:
y = 4/3x - 12
4^3 = 64
log4 64 = 3
The exponent always comes to the other side.
"return on investment" is the best measure of the efficiency of an investment, but it should be noted that there are other indicators of how well an investment is doing.
