I can answer the slopes
Answer:
1. would have a slope of 2
2. would have a slope of -1.66
3.would have a slope of 0
4. would have a slope of -13
Step-by-step explanation:
(Y2 - Y1) / (X2 -X1)
1. (9-5) / (4-2) = 4 / 2 =2
2. (-5-5) / (3 - -3) = -10 / 6 = 1.66
3. (2 - 2) / (5 - -4) = 0 / 9 = 0
4. (-7 - 6) / (3 - 3) = -13 / 0 = -13
Answer:
2) Subtraction Property of Equality Properties
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Addition Property of Equality - Adding on both sides
- Subtraction Property of Equality - Subtracting on both sides
- Multiplication Property of Equality - Multiplying on both sides
- Division Property of Equality - Dividing on both sides
- Transitive Property - If a = b and b = c, then a = c
- Symmetric Property - If a = b then b = a
Step-by-step explanation:
<u>Step 1: Define</u>
4m + 1 = 7 → 4m = 6
<u>Step 2: Identify</u>
We see that we <em>subtracted</em> on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.
I also suggest using an app called photomath. It takes you through the steps of solving the equations and gives you the answer as well.
