find the line that passes through the point (-1,3) and the point of intersection of the lines x+3y=1 and 2x-y=-5. Leave your equ
ation in point slope form.
1 answer:
To find the second point noted. Set each equation given to 0.
And
Then find the intersection point of each. I used my calculator and the intersect function but I believe you can do it mathematically as well. The point is (-2,1).
Then to build the equation I used the slope formula and used the slope to move across the graph to the y intercept.
The equation is

Reflecting the polygon FGHI across the line involves flipping the line across the line y = -1
<h3>How to reflect the polygon?</h3>The coordinates are given as:
F(2, – 1), G(5,2), H(8, 3), and I(6, 0)
The line of reflection is given as:
y = -1
To reflect the line, we apply the following rule of reflection
(x,y) (x,-y-2)
So, we have the following coordinates of the image
F' = (2, – 1)
G' = (5,-4)
H' = (8, -5)
I' = (6, -2)
See attachment for the image of the reflected polygon
