3(3x-1)^2=21 

(3x-1)^2 = 7 

3x-1 = square root of 7 

3x = square root of 7 - 1 

x = (square root of 7 - 1)/3

Use the function table to determine the slope.EXPLAIN YOUR THINKING AND HOW YOU GOT YOUR ANSWER.I WILL MARK YOU BRAINLIST!
Tom [10]

Answer:

3¼

Step-by-step explanation:

formula \frac{{y}^{2} - {y}^{1}  }{ {x}^{2} -  {x}^{1}  }

We take any of the two points shown in the question. I will take (-3, 1) and (1, 14).

x¹ = -3

y¹ = 1

x² = 1

y² = 14

Now, we sub these figures into the formula.

\frac{14 - 1}{1 - ( - 3)}

This leaves us with 14-1/1+3, which we can make into 13/4

13/4 = 3¼
