If you are trying to find slope the answer is 1/2
I'm sorry if im wrong but thats if you're trying to find slope if you're not my bad.
You use the point/slope form of the equation of a straight line
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line.
So for the first part its
y - 6 = 2(x - 5) Now simplify:-
y = 2x - 10 + 6
y = 2x - 4
You can do the others in exactl
y the same way
