Use slope formula to find slope
<span><span><span>−9−5</span><span>−/12−8</span></span>=<span><span>−14/</span><span>−20</span></span>=<span>7/10</span></span>
7/10 = m = slope
y= mx + b
y= (7/10)x + b
(8,5)
(5) = (7/10)(8) + b
b = -3/5
So....
<span>y=(<span>7/10)</span>x −<span>35
</span></span>
multiply by 10
<span>10y=7x−6</span><span>
--> -7x + 10y = -6
--> 7x - 10y = 6
So, if 7x - 10y = 3 a good model?</span>

Answer:
2. (only)
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. To determine if these are right triangles, determine if that condition is met.
1. 3^2 +5^2 = 9 + 25 = 34 ≠ (√35)^2 . . . . not a right triangle
2. 5^2 +4^2 = 25 +16 = 41 = (√41)^2 . . . a right triangle
3. 6^2 +8^2 = 36 +64 = 100 ≠ (√10)^2 . . . . not a right triangle
4. 3^2 +3^2 = 9 +9 = 18 ≠ (3√3)^2 = 27 . . . . not a right triangle
Answer:
11
Step-by-step explanation:
Those are alternate exterior angles. IF the lines A and B are parallel, then those angles are equal. Set them equal to each other and solve for x:
5x + 9 = 6x - 2
Combine like terms:
11 = x
Y because if you add them you will get 10x =-10
The y will be eliminated because you have positive 3 -4
The slope is 3/2(
0,4) and (2,7) the distance is 3 rising and 2 to the side. Remember rise over run so I would be 3/2
