Find the distance CB for the points C(8, –6) and B(6, 7).
a.
distance =
c.
distance =
b.
distance =
d.
distance =

Y = -2x + 4
7x - 2y = 3

in these systems of equations, they give you a point (1, 2) which 1 is x and 2 is y so substitute these numbers instead of x and y to find if they are a solution to it.

y = -2x + 4        (1, 2)
2 = -2(1) + 4
2 = -2 + 4
2 = 2         so this is true.

7x - 2y = 3        (1, 2)
7(1) - 2(2) = 3
7 - 4 = 3
3 = 3         so this is true.

the answer is B and C and F.

hope this helps, God bless!
