Answer:
<h2>y = 3.5x - 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<h3>y = mx + b</h3>
m - slope
b - y-intercept
We have y-intercept b = -2. Substitute:
<h3>y = mx - 2</h3>
We have the point (4, 12) → x = 4, y = 12. Put them in the equation:
12 = 4m - 2 <em>add 2 to both sides</em>
14 = 4m <em>divide both sides by 4</em>
14/4 = m → m = 3.5

Answer:
![\text{B)} \quad e^5=3x](https://tex.z-dn.net/?f=%5Ctext%7BB%29%7D%20%5Cquad%20e%5E5%3D3x)
Step-by-step explanation:
The exponential function and the natural log are inverse functions:
e^ln(x) = x
Using both sides of your given equation as exponents for e, we have ...
e^(ln(3x)) = e^5
From the above, we know that ...
e^(ln(3x)) = 3x
so we can substitute that into the preceding equation to get ...
3x = e^5
Swapping sides of the equal sign gives an equation that matches choice B:
e^5 = 3x
