Which equations represent the line shown in the graph?

zaharov [31]

The given graph is a straight line passing through points (-4, -3) and (1, 5)
Equation in point slope form is y + 3 = (5 - (-3))/(1 - (-4)) (x - (-4))
y + 3 = 8/5(x + 4)
y + 3 = 8/5x + 32/5
y = 8/5x + 32/5 - 3
y = 8/5x + 17/5

Multiplying through by 5 gives
5y = 8x + 17
-8x + 5y = 17
Options B and C are the correct answers.

const2013 [10]

Answer:

Sokhem: 30
Chanda: 18

Step-by-step explanation:

Let c represent Chanda's age now. In six years, the Sokhem's age will be 2c. At that time, the sum of their ages is ...

(c+6) +2c = 60

3c = 54 . . . . . . . . subtract 6, collect terms

c = 18 . . . . . . . . . . divide by 3

Chanda is 18, Sokhem is 30.

_____

<em>Check</em>

In 6 years Chanda will be 24, Sokhem will be 36. The sum of their ages then will be 24+36 = 60. Since Chanda is 18 now, Sokhem's age then will be 2 times Chanda's age now.
