Could someone explain this please, I'm horrible at math:
Find the slope of any line parallel to the line through points (18, 3) and (2, 1).

(3-1)/(18-2) = 2/16 = (1/8)
(1/8) is the slope. Rise over run. Difference in Y values divided by difference in X values.

The first thing you need to do is find the slope of the line through the 2 points you're given. The equation is (y2-y1)/(x2-x1). this would be (1-3)/(2-18).
this equals -2/-16, which simplifies to 1/8.
Parallel lines have the same slope, so the answer would be 1/8.

The form of a line is y=mx+c (depending where you come from). Because we are looking for a parallel the c is irrelevant. We can get the differences between the corresponding points and convert that to a ratio. 16:2 Get that 2 to a 1 and there you have it the slope off the line is 8

The slope is 8

Given a line y=mx+b, the slope m can be determined from
m= y2-y1 / x2-x1, where (x1,y1) and (x2,y2) are any two different coordinates on the line. Any other line with slope m is parallel to the line that you worked with. Now do it yourself.
