Find the value of r so that the line through (-4,3) and (r,-3) has a slope of 2/3.
Tems11 [23]

Answer:

<h3>r = -13</h3>

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the slope m = 2/3 and the points (-4, 3) and (r, -3). Substitute:

\dfrac{-3-3}{r-(-4)}=\dfrac{2}{3}

\dfrac{-6}{r+4}=\dfrac{2}{3}        <em>cross multiply</em>

2(r+4)=(-6)(3)        <em>divdide both sides by 2</em>

r+4=(-3)(3)

r+4=-9       <em>subtract 4 from both sides</em>

\boxed{r=-13}

lapo4ka [179]
Given that Johney's baseball had raised $1,456 out of $2,000 they need to play the tournament.

Amount of money they still need to raise is given by $2,000 - $1,456 = $544.

Given that there is a total of 11 players in the team. Let x represent the total amount each player needs to raise, then x = $544 / 11 = $49.45

Therefore, each player needs to raise $49.45
