y = [? ]x +
Enter the answer that
belongs in [?].

Step-by-step explanation:

The equation that describes how x

and y are related is given in the slope-intercept form,

Where, m = slope, and b = y-intercept.

Let's find the value of m and b using the table of values given.

Using two of the pairs given, (-2, -8) and (-1, -5),

Substitute x = -2, y = -8, and m = 3 in to find the value of b.

Thus:

Add 6 to both sides

Substitute m = 3 and b = -2 in .

The equation that describes how x

and y are related would be:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

2 over 5 and 4 over 15
