Answer:
Third option: 
Step-by-step explanation:
<h3><em> The correct form of the exercise is: "The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is

. What is the slope-intercept form of the equation for this line?"</em></h3><h3><em /></h3>
<em> </em>The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Given the equation of the line in Point-Slope form:

You need to solve for "y" in order to write the given equation of the line in Slope Intercept form.
Then, this is:

You can identify that the slope "m" is:

And the y-interecept "b" is:

Find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve
Putting it into a calculator, we get 0.125 as our answer
Answer:
$20.16
Step-by-step explanation:
First we need to find 12% of his current hourly rate, 12% is our decimal multiplier here so we use 0.12. In order to get 12% we need to multiply our decimal by $18 which is:
$18 × 0.12 = $2.16
Now let's add this 12% on top of his current hourly rate.
$18 + $2.16 = $20.16
And that's the final answer.
