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:

Assuming BOD and AOC are straight lines.
Area of the rectangle = 4 x ΔAOD
Area of the rectangle = 4 x 10
Area of the rectangle = 40 unit²
Area of ΔABC = 1/2 x 40
Area of ΔABC = 20 unit²
Answer:
50+n
Step-by-step explanation:
distributive property: 10 times 5 equals 50.
you are left with 50 plus n.
Answer: 5(x-1)
