If the principal randomly selects a student in grade 12 so this means we focus on just the "grade 12" row. No other rows will be looked at here<span> what is the probability that the student is in favor of extending the school day?"</span> find the number in favor (who also happen to be in grade 12) then divide that number by the total number in grade 12  make sense.          

so it would be .37

Write in standard form an equation for the line with slope 1/3 through<br> the point (2,-2).
Alexxandr [17]

Answer:

x - 3y = 8.

Step-by-step explanation:

Use the point-slope form of the equation of a line:

y - y1 = m(x - x1)  where m = the slope and (x1, y1) is a point on the line.

So substituting the given values:

y - (-2) = 1/3(x - 2)

y + 2 = 1/3x - 2/3     Multiply through by 3:

3y + 6 = x - 2

x - 3y  =  6 + 2

x - 3y = 8  <---- Standard Form.
