Step-by-step explanation:
4 units up and 8 units to the right will align
Step-by-step explanation:
Hey there!
Given;
Midpoint is (-1,3) and one endppint is; A(4,-1).
Let the coordinates of C be (x,y).
<u>Use</u><u> </u><u>the</u><u> </u><u>midpoint</u><u> </u><u>formula</u><u>.</u>
<u>
</u>
<u>Put</u><u> </u><u>all values</u><u>. </u>
<u>
</u>
Since, they are equal, equating with their corresponding elements we get,
![- 1 = \frac{4 + x}{2}](https://tex.z-dn.net/?f=%20-%201%20%3D%20%20%5Cfrac%7B4%20%2B%20x%7D%7B2%7D%20)
<u>Simplify</u><u> </u><u>it</u><u>. </u>

<u>Therefore the</u><u> </u><u>another</u><u> </u><u>endpoint is</u><u> </u><u>C</u><u>(</u><u>-6</u><u>,</u><u>7</u><u>)</u><u>.</u>

Answer:
B. 2.
Step-by-step explanation:
You can find the average by substituting the given values in the function, then do an arithmetic average with results.
So, for X = - 1 you get f(-1) = 1
For X = 0 you get f(0) = 3
So, the average with 1 and 3 is 2. Because you sum numbers which results 4, and then divided by 2 (the amount of numbers involved in the average).
Answer:
15
Step-by-step explanation:
To find the y intercept set x=0
You are given two points: (7,-6)(-4,27)
y=mx+b
y2-y1=x2-x1
x1=7
y1=-6
x2=-4
y2=27
27-(-6)/-4-7=27+6/-4-7=33/-11=-3
y=-3x+b
-6=-3(7)+b
-6=-21+b
+21 +21
b=15 so, y=-3x+15
PLUG IN O TO THAT EQUATION
y=-3(0)+15
Your y intercept would be 15
