Example #1: y = 4x + 5 y = -4x + 5 | Different:
Same: The Slopes The y-intercepts One is +4 and the other is -4 Both +5 |
Example #2: y = 7/4x -9 y = 7/4x +9 | Different:
Same: The y-intercepts The slopes One is -9 and the other is +9 Both +7/4 |
Example #3: y = -3x + 8 y = 8x - 3 | Different:
Same: The Slopes and y-intercepts Nothing! |
