Step-by-step explanation:

(Y2 - Y1) / (X2 -X1)

1. (9-5) / (4-2) = 4 / 2 =2

2. (-5-5) / (3 - -3) = -10 / 6 = 1.66

3. (2 - 2) / (5 - -4) = 0 / 9 = 0

Virty [35]

Answer:

d) x=4

Step-by-step explanation:

\sqrt{x} +5 = \sqrt{x + 45}

(\sqrt{x} +5)^{2}   = (\sqrt{x + 45})^{2}

x + 10\sqrt{x} +25 = x + 45

10\sqrt{x}  = 20

divide 10 in both sides

(\sqrt{x}){2}  = (2){2}

x=4
