[ Please help! ] Choose the equation that represents the graph below.
Kitty [74]

The line crosses the x -axis at point (9,0) and the y-axis at point (0,6).

If the equation of the line is y=kx+b, then substitute the coordinates of the points into this equation:

1) 0=9k+b;

2) 6=b.

Substitute the second equation into the first:

9k+6=0,\\ \\k=-\dfrac{2}{3}.

The equation of the line is

y=-\dfrac{2}{3}x+6.

Answer: option C

Kim's weekly pay is two thirds of Alicia's.Together they earn $600 per week
garik1379 [7]
A + k = 600
k = 2/3a

a + 2/3a = 600
3/3a + 2/3a = 600
5/3a = 600
a = 600 * 3/5
a = 1800/5
a = 360

k = 2/3a
k = 2/3(360)
k = 720/3
k = 240

so Kim's pay is $ 240 and Alicia's pay is $ 360
