Find the distance between the points (4, –2) and (0, 10).

madam [21]

$A(4,-2) \\B(0, 10) \\AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\AB=\sqrt{(0-4)^2+(10-(-2))^2} \\AB=\sqrt{16+144} \\AB=\sqrt{160}\approx\boxed{12.65} \\$

The answer is D.

Hope this helps.

$The\ point-slope\ form:y-y_1=m(x-x_1)\\---------------------\\m=\frac{3}{5}\\\\(4;-6)\to x_1=4\ and\ y_1=-6\\\\subtitute:\\\\y-(-6)=\frac{3}{5}(x-4)\\\\\boxed{y+6=\frac{3}{5}(x-4)}$

Answer:

y = 8

Step-by-step explanation:

It can be useful to write down the values of corresponding parts of the figures. This can help you see the ratio between corresponding measures. Here, we're concerned with sides.

AB = ?, FE= 6

BC = 10, EC = 5 . . . . . a ratio of 2:1

CD = ?, CG = ?

DA = y, GF = 4

So, the proportionality of the sides in these similar figures means ...

y/4 = 10/5

y = 4×10/5

y = 8 . . . . multiply by 4
