Algebra 2 Grade 11 Can anyone please help me soon as possible?

Find the equation of a line given the point (4, 3) and slope 2.

Here are the choices:

y = 2 x + 7

y = 2x + 3

y = 2x - 5

y = 2x + 1

y = 2x - 5

Step-by-step explanation:

y - 3 = 2 (x - 4)

y = 2x - 8 + 3

y = 2x - 5

answer: i believe the answer is e

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
