Choose the equation that represents the graph below: (1 point) Graph of a line passing through points 0 comma 6 and 9 comma 0 y

aleksklad [387]

Answer:

Option C is correct.

Equation of a line $y=\frac{-2}{3}x+6$ passing through (0,6) and (9,0).

Explanation:

Given the two points (0, 6) and (9 ,0).

To find the equation for the given two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is,

$y-y_{1}=m(x-x_{1})$ ; where m is the slope and is given by:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

First find the slope m:

$m=\frac{0-6}{9-0} =\frac{-6}{9} =\frac{-2}{3}$

Substitute this value in equation of line:

$y-6=\frac{-2}{3} (x-0)$ or

$y-6=\frac{-2}{3} x$

⇒ $y=\frac{-2}{3}x+6$

Therefore, the equation for the given point is: $y=\frac{-2}{3}x+6$

Liam has 3 games and 10 songs on his computer. How many outcomes are possible when randomly choosing a song and a game?

cupoosta [38]

3 outcomes are possible because you only have 3 games on it, and it is mandatory to only have 1 game and 1 song at a time.

$= 12 + {4y}^{2} - 7$

$= 12 + {4(3)}^{2} - 7$

$= 12 + 4(9) - 7$

$= 12 + 36 - 7$

$= 48 - 7$

$= 41$
