1. which ordered pair is a solution of the linear equation shown in the graph above?
a (02, 0)
b(1, 3)
c(-1, 1)
d (0, -1)
2. which ordered pair is a solution of y = x - 4
a(-1 -5)
b (0, -3)
c (2, 6)
d (3,1)

picture is attached, explanation is not expected but is appreciated. you.

a and c

step-by-step explanation:

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
