Write an equation for the ine that passes through the point (-4,1) and that has a slope of 3. Give your answer in slope intercept form
OA y = 3x + 13
B. y = 3x - 13
cy= - 3x - 13
Dy=-3x + 13

The best choice is option A. y = 3x + 13

Step-by-step explanation:

slope = 3

y = mx + b

1 = 3(-4) + b

1 = -12 + b

+12    +12

13 = > y-intercept

Final equation --> y = 3x + 13

The correct choice is option A. y = 3x + 13

he kicked it up? is this the answer ?

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
