What is the slope and y intercept of the following linear function: 2x+y=7 show your work(preferably through y=mx+b form) < 3 i am also awarding max points for this question

y = mx + b

"m" is the slope, "b" is the y-intercept

2x + y = 7     Isolate the "y" by subtracting 2x on both sides

2x - 2x + y = 7 - 2x

y = 7 - 2x     or    y = -2x + 7

The slope is -2

The y-intercept is 7

c

step-by-step explanation:

c

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
