Answer:

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

Step-by-step explanation:

Use the slope-intercept form:

$y=mx+b$

m is the slope and b is the y-intercept. Looking at the graph, you can find the y-intercept. The y-intercept is the point where x equals 0:

$b=-6$

$y-intercept=(0,-6)$

To find the slope, take any two points from the line:

$(6,-2)(3,-4)$

Use the slope formula for when you have two points:

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}$

The rise over run is the change in the y-axis over the change of the x-axis. Insert the appropriate values:

$(6(x_{1}),-2(y_{1})\\(3(x_{2}),-4(y_{2})$

$\frac{-4-(-2)}{3-6}$

Simplify parentheses (two negatives makes a positive):

$\frac{-4+2}{3-6}$

$\frac{-2}{-3}$

Simplify (two negatives make a positive):

$m=\frac{2}{3}$

The slope is $\frac{2}{3}$ and the y-intercept is $-6$ . Insert these into the equation:

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

Finito.

3/11 de una caja contiene 18 galletas, cuantas galletas contiene una caja?

Fynjy0 [20]

Answer:

66 galletas

Step-by-step explanation:

Si 3/11 de una caja contiene 18 galletas entonces matematicamente significa que:

$\frac{3}{11}g=18$

Donde g son las galletas, ahora vamos a aislar la variable g:

$\frac{3}{11}g=18\\\\(\frac{11}{3}) \frac{3}{11} g=18 (\frac{11}{3})\\\\g= \frac{198}{3}=66$

Entonces una caja contiene 66 galletas

Solve the multi step literal equation: solve equation for A b^2A^2-3g=q

I am Lyosha [343]

Answer:

A = ± $\sqrt{\frac{q+3g}{b^2} }$

Step-by-step explanation:

Given

b²A² - 3g = q ( add 3g to both sides )

b²A² = q + 3g ( divide both sides by b² )

A² = $\frac{q+3g}{b^2}$ ( take the square root of both sides )

A = ± $\sqrt{\frac{q+3g}{b^2} }$
