Can you please help me in this two question pleaseee :( this class is of algebra and I don’t understand 1. What does the sign of the correlation coefficient (`r=-0.83`) tell you about the relationship between the number of bacteria colonies and the concentration of antibiotic in the dish?

2. What does the numerical value of the correlation coefficient (`r=-0.83`) tell you about the relationship between the number of bacteria colonies and the concentration of antibiotic in the dish?

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
