Answer: The slope of parallel lines are the same
Explanation:
There are not triangles in the image, but instead two lines creating a corner, they want you to connect the opposite corners of each of these sets of lines to create a triangle.
The bigger set of lines is up 2 right 8. slope is rise/run so the slope is 2/8 or if we simplify 1/4
The smaller set of lines is 1 up 4 right. slope is rise over run so the slope is 1/4.
The problem tries to confuse you by not connecting those lines and by having the bigger one go up first then right, and then the smaller one go right first and then up.
But as you can see the parallel lines both have a slope of 1/4
the only difference between parallel lines is the 'b' in the equation y=mx+b
