Example 4 Find the slope of  x  –  y  = 3 using coordinates.  To find the slope of the line, pick any two points on the line, such as  A  (3, 0) and  B  (5, 2), and  calculate the slope.  Example 5 Find the slope of  y  = –2  x  – 1 using coordinates.  Pick two points, such as  A  (1, –3) and  B  (–1, 1), and calculate the slope.  Example 6 Find the slope of

Unformatted text preview: x – 2 y = 4 using coordinates. Pick two points, such as A (0, –2) and B (4, 0), and calculate the slope. Looking back at the equations for Example (a), (b), and (c) written in y-form, it should be evident that the slope of the line is the same as the numerical coefficient of the x-term....
