Calculate the slope of the straight line between each set of two points.
(X_{1},Y_{1)}  (X_{2},Y_{2)}  Slope 
(1,1)  (4,7)  (7  1)/ (4  1) = 6/3
= 2

(1,8)  (3,0)  (0  8)/ (3  1) = 8/2
= 4

(3,8)  (0,2)  (2  (8))/ (0  (3)) = 6/3
= 2

(8,3)  (4,6)  (6  (3))/ (4  (8)) = 3/12
= 0.25

The various resources listed below are aligned to the same standard, (8EE06) taken from the CCSM (Common Core Standards For Mathematics) as the Expressions and equations Worksheet shown above.
Use similar triangles to explain why the slope m is the same between any two distinct points on a nonvertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.
Similar to the above listing, the resources below are aligned to related standards in the Common Core For Mathematics that together support the following learning outcome:
