First off, this is a homework question, but an example so answer is given. need help understanding it.

-Show that ht elines given by the equations below are coincident:

L: 2x - y = 5

M: -4x + 2y = -10

Solution: Write each equation in slope-intercept form:

L: 2x - y = 5

-y = -2x + 5

y = 2x - 5

M: -4x + 2y = -10

2y = 4x - 10

y = 2x - 5

Answer: The lines L and M have a slope of 2, and the same y intercept (0,5) so they are coincident.

I dont understand how they got that answer of slope of 2 and y intercept of (0,5)

?

Thanks everyone!
