Question

Try finding the slope of a line joining the following pairs of points:
(x, x+2) and (x+2, x+4)

Answer 1

Do you remember the equation of line slope?

Answer 2

noooooooooooooooooooooooooooooooo

Answer 3

It already answered in chat. But for clarity, if you know two points (x1,y1) and (x2,y2), you can find the slope of line joining that point with this formula:
m=(y2-y1)/(x2-x1)

Answer 4

equation is:

gradient = (y2 - y1)/(x2-x1)
=(x+4 - x+2)/(x+2-x)
=2/2
=1
