Answer:
(10,9) P=10
Step-by-step explanation:
find the slope first: y2-y1/x2-x1=(3-1)/1-(-2)=2/3
y=2/3x+b
find b:
3=2/3(1)+b
b=3-2/3
b=7/3
now we find P
(p,9) input the y in the equation
y=2/3 x+7/3
9=2/3x+7/3
9-7/3=2/3x
x=10
-16 use PEMDAS to find answer
The answer is B because its 9 hundred and thousandths is the smallest place
Answer:
L (4,-5)
Step-by-step explanation:
The transformation rule is (x,y) → (-y,-x) . This means that you are going to exchange your x and y and switch their signs.
1. Exchange - First you switch your points. (5,-4) → (-4,5)
2. Switch signs- -4 converts to 4 and 5 converts to -5
So your answer is L' (4,-5)
The slope is negative one half because perpendicular lines always have slopes that are opposite reciprocals
meaning not only are they reciprocals meaning 1 over the number (or flipping the numerator and the denominator of a fraction) you also change the sign
