Which equation describes this line?
yawa3891 [41]

Answer:

The equation of line with given points is  y - 4 = 3 ( x + 2 ) .

Step-by-step explanation:

Given as :

The points of line are ( 1 , 13 )   and    ( - 2 , 4 )

The point slope intercept equation of line is

y - y_1 = m ( x -  x_1 )

Where m is the slope of line

So , Slope , m = \frac{y_2 - y_1}{x_2 - x_1}

Or, m =  \frac{4 - 13}{ - 2 - 1}

Or, m =  \frac{ - 9}{ - 3}

∴    m = 3

Now The equation of line is

y - y_1 = m ( x -  x_1 )

Or. y - 13 = 3 ( x -  1 )

Or, y - 13 = 3 x - 3

Or, y = 3 x - 3 + 13

∴   y = 3 x + 10

I.e y - 4 = 3 x + 6

Or, y - 4 = 3 ( x + 2 )

Hence The equation of line with given points is  y - 4 = 3 ( x + 2 ) . Answer

Argument
Your chances of throwing a 6 = 1/6

Expected Throws = P(6) * Total Throws
Expected Throws = 1/6 * 120
Expected Throws = 20
