Answer:
<em>y-9=0(x-6)</em>
<em>Or, equivalently: y=9</em>
<em>This represents a horizontal line</em>
Step-by-step explanation:
<em>Equation of the line</em>
The point-slope form of the equation of a line is:

Where m is the slope and (h,k) is a point through which the line passes.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

The points are (6,9) and (7,9). These points dfine a horizontal line, as we'll see later.
The slope is:

m=0
Now compute the equation in point-slope form:
y-9=0(x-6)
Solving for y:
y=9
This represents a horizontal line
Answer:

Step-by-step explanation:




Using proportions, it is found that:
- In an 8-hour day, she keys 48 pages.
- For a day, her gross earnings are of $72.
- For a week, her gross earnings are of 72 x 7 = $504.
<h3>Proportions:</h3>
This question is solved using the proportions given, which are:
- Payment of $1.50 per page of 30 lines.
- Retha keys 6 pages per hour.
Hence, in an 8-hour day, she keys 6 x 8 = 48 pages.
Since she earns $1.50 per page, for a day, her gross earnings are of 48 x 1.5 = $72.
Considering a week has 7 days, for a week, her gross earnings are of 72 x 7 = $504.
