4. Point E is located at (–2, 2) and point F is located at (4, –6). What is the distance between points E and F?
a. square root of 52
b. square root of 28
c. 10
d. square root of 20
5. In which quadrant is the point (x, y) located if x is negative and y is positive?
a. II
b. III
c. IV
d. I
6. Point A(8, –10) is reflected over the yaxis. Write the coordinates of A'.
a. (–8, –10)
b. (8, 10)
c. (8, –10)
d. (–8, 10)

help me plz

4. The distance is ((y2y1)^2 + x2x1)^2)^.5
plugging the numbers in:
((62)^2 + (4 +2)^2)^.5 =
square root of (64 + 36)
a. square root of 52
Just type in 52 ^ 0.5 into your calculator
imagine your axes are centered on a clock. The first quadrant (quarter on a clock) is x positive, y positive
2nd quadrant x positive, y negative
3rd quadrant x negative, y negative
4th quadrant x negative, y positive
6. When a point is reflected over the yaxis, the value of the x coordinate is multiplied by a negative 1, and the value of the the y coordinate stays the same 
4. d=sqrt[(2+6)² +(2+4)²]=10
c. 10
5. a. II
6. a. (–8, –10) 
Wat?

Elena are u sure they are right

which one of them are right

Sorry  but my math skills don't extend this far.

4. Don't know how Jennifer got 64+36 = 52
used to be 100 when I went to school
4. c
5. a

Elena is right, her answers agree with mine
