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
