Question

Point P is plotted on the coordinate grid. If point S is 10 units to the left of point P, what are the coordinates of point S?

A (6, −14)
B (−4, −4)
C (−4, −14)
D (6, 4)

Answer 1

P = (6,-4) you know that point S is to the left of point p so that's in quadrant 3 (-x,-y) so right away both points will be negative.

Answer 2

yEAH

Answer 3

Yeah*

Answer 4

so we can actually just use the distance formula to solve this question,

Answer 5

\[\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}} = Distance \]

Answer 6

yikes

Answer 7

how do you do that?

Answer 8

it's not that bad as it looks

Answer 9

Oh

Answer 10

lol ok

Answer 11

so if we take that point say

(-4,-4)

and

(6,-4)

and subtract the x and y values

Answer 12

\[\sqrt{ (-4-6)^{2}+(-4-(-4))} = \sqrt{(10)^{2}+0} = \sqrt{100} = 10\]

Answer 13

so the distance formula tells you the distance between two points.
