Answer: Third option.
Step-by-step explanation:
By definition, the slope of a line can be calculated with the following formula:
Since you need to solve for 
to find an equivalent expression, you can apply these steps:
1. You must multiply both sides of the equation by 
:
2. Finally, you must add 
to both sides of the equation:
$9802.90
17.4% = 0.174
so retail price = 8,350 + 8,350 * 0.174
= $9802.90
Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.
Moving left or down causes the coordinates to be going negative.
Moving right or up causes the coordinates to be positive.
Original point (10, 1).
Down 1 unit:
(10, 1 - 1) = (10, 0)
Left 7 units:
(10 - 7, 0) = (3, 0)
You end at (3, 0)
Acute: anything less than 90 but greater than 0
so, m<CAD
right: angles at exactly 90 degrees, so m<AEC,
and obtuse angles are anything greater than 90 but less than 180 degrees,
so CDA (you can tell by the picture that it is bigger than 90- 90 degrees is exactly perpendicular)
