Answer:
D is the correct answer.
Step-by-step explanation:
First find the slope: 2-5/8-9=3 So slope is 3
(y-y1)=m(x-x1) is the point slope formula
plug in the numbers (y-5) = 3(x-9)
y-5 = 3x-27
y=3x-22
<span><u><em>The correct answers are:</em></u>
a line of symmetry will connect a vertex and a midpoint of an opposite side
it has 7-fold symmetry.
<u><em>Explanation</em></u><span><u><em>: </em></u>
A line of symmetry is a line that we can use to <u>"fold"</u> a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex.
Since there are 7 vertices, there will be 7 lines of reflection.</span></span>
Answer:
1/4
Step-by-step explanation:
minus power can be moved below the division line as 2^2/2^4=4/16
- Slope Formula:
So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:
Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>
