Answer:
<h3>The answer is option D.</h3>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
Slope of the line using points ( 5 , - 1) and
( - 5 , 2) is
m = 2+1/ -5-5 = - 3 / 10
Equation of the line using point ( 5 , - 1) is
y + 1 = -3/10(x - 5)
y = -3/10x + 3/2 - 1
The final answer is
<h3>y = - 3/10x + 1/2</h3>
Hope this helps you.
From one vertex of an octagon you can draw 5 diagonals.
There are 8 vertices in an octagon, and we are choosing one as our starting vertex. There are then 7 vertices left to draw a line to, but 2 of the vertices are already connected to our main vertex (because they are connected along the side of the octagon). That leaves 5 vertices to draw a diagonal to from our original vertex.
