Graph each line. Give the slope-intercept form for all standard form equations.

Mathematics

Nuetrik [128]3 years ago

Answer:

y = 1/3x + 5

Step-by-step explanation:

Since the slope-intercept form is y=mx+b, you need to start by rewriting this in slope-intercept form, which you can write this as 3y = 15 + x. You get this by adding X to both sides.

Then, divide everything by Y, which in this case is 3.

3y Divided by 3 is 1, or Y.

15 Divided by 3 is 5.

x, or 1x, divided by three, is 0.3 forever repeating. However, you rewrite this as a fraction, due to slope-intercept form.

That's how you get the final answer, the final answer being y = 1/3x + 5.

Help please! I do not exactly understand how to do this. Thanks!
Radda [10]

X and Y are supplementary, that means X + Y = 180.

But we have, X  = Y +24, then

X + Y = Y + 24 + Y = 2Y + 24 = 180

Then

2Y = 156

Y = 78

Then X = 78 + 24 = 102.

  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

y = -23(x + 9) + 4

y = 0

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in <em>y</em>:                                                                                                  0 = -23(x + 9) + 4
  2. [Subtraction Property of Equality] Subtract 4 on both sides:                        -4 = -23(x + 9)
  3. [Division Property of Equality] Divide -23 on both sides:                                4/23 = x + 9
  4. [Subtraction Property of Equality] Subtract 9 on both sides:                        -203/23 = x
  5. Rewrite:                                                                                                             x = -203/23
