The rate of change of the linear relationship is -1.
Explanation:
It is given that there is a linear relationship between all these points, these points lie on a straight line.
The equation to find the slope passing through two points and
is given by
Substituting the points and
, we get,
Thus, the slope is -1.
Thus, the rate of change of the linear relationship is -1.
Answer:
x = -2
y = -1
(-2, -1)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = x + 1
3x + 3y = -9
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 3x + 3(x + 1) = -9
- Distribute 3: 3x + 3x + 3 = -9
- Combine like terms: 6x + 3 = -9
- Isolate <em>x</em> term: 6x = -12
- Isolate <em>x</em>: x = -2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x + 1
- Substitute in <em>x</em>: y = -2 + 1
- Add: y = -1
<u>Step 4: Graph systems</u>
<em>Check the solution set.</em>
I'll break it down for you. Here are the main points:
-has 2 large servings
-made from 9 pints
-x represents how many pints
-y represents how many servings
Now that we know this we can find what each serving comes out to be for example:
=4.5 or 4
So for each serving it will come out to be 4.5 pints.
Now that we know this we can figure out the slope to find what the equation which is for example the slope for this equation would be rise over run for example:
=
=
when simplified.
So our equation would be (also the answer) y=x
