How to find the slope of a line when given two points?

Mathematics

There is a slope formula for this.
slope = (y2 - y1) / (x2 - x1)

example : lets say u r given 2 sets of points....(1,2) and (3,4). First, we must label out points
set 1:  (1,2)....so lets label these : x1 = 1 and y1 = 2
set 2 : (3,4)...and we label these x2 = 3 and y2 = 4

now we sub these into our formula and solve
slope = (y2 - y1) / (x2 - x1)
slope = (4 - 2) / (3 - 1) = 2/2 = 1
so the slope of these 2 sets of points is 1.

one important thing to remember, ur points may not always be positive...so pay close attention to ur signs

These two lines create vertical angles, which are congruent. That means angle z = 60 degrees. Since angle z and the angle represented by the expression 6x + 60 are supplementary (they are adjacent angles that add to equal 180 degrees), you can set up the following equation to find x:

6x + 60 + 60 = 180
6x + 120 = 180
6x = 60
x = 10

Answers:
x = 10
z = 60
