Y = -1/3x + 2.....the slope here is -1/3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, flip the slope and change the sign. So the slope is -1/3.....flip it and it becomes - 3/1....change the sign and it becomes 3/1 or just 3. So ur perpendicular line will have a slope of 3.
y = mx + b
slope(m) = 3
(-3,-5)....x = -3 and y = -5
now sub into the formula and find b, the y int
-5 = 3(-3) + b
-5 = -9 + b
-5 + 9 = b
4 = b
so ur perpendicular equation is : y = 3x + 4 <===
The probability of the weather being nice the next day or not depends on whether the sky is red at night or not. The sailor can use probability to tell whether the weather will be nice the next day or not. If the sky is red that night , then the next day will bring nice weather, but if the sky is not red that night, the weather wont be good the next day. (Don’t know if this is right or not but I hope it helps (: )
Answer:
Step-by-step explanation:
<u>ANSWER</u>
The vertex form is 
<u>EXPLANATION</u>
We use completing squares
We factor -4 out of the first two terms
We add and subtract 
, that is coming from, 
.
The expression in the first parenthesis is now a perfect square.
The function is now in the form,
, where 
is the vertex
Hence the vertex is
