The graph of a line passes through the points (0, 5) and (-10, 0). What is the equation of the line?

1 answer:

5 0

(0,5)(-10,0)
slope = (0 - 5) / (-10 - 0) = -5/-10 = 1/2

y = mx + b
slope(m) = 1/2
use either of ur points (0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = 1/2(0) + b
5 = b

so ur equation is : y = 1/2x + 5

How many units long is a segment whose endpoints are (2,3) and (7,15)?

Ahat [919]

Answer:

13 units

Step-by-step explanation:

Distance formula: $d = \sqrt{(x2-x1)^2 + (y2-y1)^2}$

Simply plug in your variables

$d = \sqrt{(7-2)^2 + (15-3)^2}$

$d = \sqrt{5^2 + 12^2}$

$d = \sqrt{25 + 144}$

$d = \sqrt{169}$

d = 13

Adam cut a piece of string 42 inches long into 2 pieces. The ratio of the length of the 2 peices is 3:4, what is the length, to

jek_recluse [69]

Answer:

Shorter piece length is 18 inches

Step-by-step explanation:

Let's marked first piece with x and second with y

x + y = 42

Given ratio is x : y = 3 : 4

From this proportion we get

x = 3 c and y = 4 c where c is coefficient of proportionality

when we replace this in initial equation we get

3 c + 4 c = 42 => 7 c = 42 => c = 42/7 = 6 c = 6

x = 3 · 6 = 18 inches and z = 4 · 6 = 24 inches

shorter piece is x = 18 inches

God with you!!!
