What is the equation of the line with the given slope and y-intercept? Choose the correct answer in slope-intercept form and sta
kari74 [83]

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y-intercept )

here m = \frac{1}{3} and b = 13, hence

y = \frac{1}{3} x + 13 ← in slope- intercept form

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and AB, C are integers )

multiply all terms in the slope-intercept form by 3

3y = x + 39 ( subtract 3y from both sides )

0 = x - 3y + 39 ( subtract 39 from both sides )

x - 3y = - 39 ← in standard form

4. For each function, write the rule in vertex form and find the coordinates of the max/min point on its graph.
kakasveta [241]
'Vertex form', having just googled it, is another name for completing the square, which I have done extensively at school. This involved converting:
f(x) = ax^2 + bx + c --> f(x) = a(x-b)^2 + c

In the completed-square form, (b, c) are the co-ordinates of the vertex (which is the maximum/minimum point). So for part a:

- Here is the original
  f(x) = x^2 + 12x + 11

-  Halve the x-coefficient (the number before x) and use it as -b in the vertex form described above. You must then calculate the square of this number and minus it at the end because when you multiply it out, this is the surplus you will make along with x^2 + 12x:
  f(x) = (x + 6)^2  - 36 + 11

- Tidy this up by collecting the constant (just number) terms together:
  f(x) = (x + 6)^2 - 25

- Using the form a(x - b)^2 + c, we can work out that b = -6 (because -b = 6) and c = -25. This gives us the vertex (-6, -25) which is a minimum point because the graph is a positive quadratic, giving us the characteristing 'U' shape which has a bottom. If it were a negative quadratic (denoted by a negative x^2 coefficient), the vertex will be a maximum point because it has an 'n' shape instead.

- To solve the equation from here, make the function equal to zero:
  (x + 6)^2 - 25 = 0

- Then take 25 to the other side:
  (x + 6)^2 = 25

- Next, square-root both sides:
  x + 6 = <span>±5

- Rearrange to finish:
  x = -6 </span><span>± 5 = -1 or -11

- Therefore, the roots (solutions) to the equation x^2 + 12x + 11 = 0 are x = -1 or -11

This method will work the same for the other equations up there too, so I will leave them for you to do.

I hope this helps
