Answer:
i dont know for sure but it says possible order pairs
6,12
Slope: (y2-y1)/(x2-x1)
(8-2)/(1+1) = 6/2 = 3
The slope is 3
Answer:
add both x coordinates and divide them by 2.
add both y coordinates and divide them by 2.
Now final product should be (x,y)
Step-by-step explanation:
Example.
let's take 2 points:
(2,5) and (7, 9)
let's add both x coordinates.
2+7 = 9
now add both y coordinates.
5+9 = 14
Now divide both by 2.
Final answer should be (4.5, 7) = this is your midpoint
Answer:
and 
Step-by-step explanation:
Think about it.
What two numbers multiply to -15 and add up to 2?
The answers are 5 and -3.
So plug that into the factored form of a parabola.
To find the x-intercepts, plug in 0 for 
.
Since we are multiplying, at least one of the terms has to equal 0.
So the x-intercepts are and .
Perpendicular slopes multiply to -1, so are <em>negative reciprocals.</em>
-1 / -3 = 1/3
Answer: B. 1/3
