y = 0x - 6     has a slope of 0
If you graph several points for x where y = -6,  <em>(0, -6), (1, -6), (2, -6), etc  </em>you will see that it creates a horizontal line

Answer:
A, is the answer.
Step-by-step explanation:
If you take two points and then find the slope between them you'll find that it is 1.5.
You could also make a T-chart or plug in the x coordinates into each possible equation and see which one matches the corresponding y coordinate. 
 
        
             
        
        
        
Step-by-step explanation:
f(x) = 3x² - 2x + 7
f(-2) = 3(-2)² -2(-2) + 7
 = 3(4) + 4 + 7
 = 23
