Probability =

(number of ways to succeed) / (total possible outcomes) .

There are 6 total possible outcomes of rolling one honest die.
Only one of them is a ' 4 '.

-- So the probability of rolling a '4' on the first roll is 1/6 .

-- The probability of rolling a '4' on the second roll is 1/6 .

-- The probability of BOTH events is

(1/6) x (1/6) = 1/36 = (2 and 7/9) percent .

What is an equation of the line that passes through the points

zubka84 [21]

Answer <u>(assuming it can be in slope-intercept form): </u>

y = x - 5

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$ , and substitute the x and y values of the given points into it. Then, solve:

$m = \frac{(2)-(1)}{(7)-(6)} \\m = \frac{2-1}{7-6} \\m = \frac{1}{1} \\m = 1$

2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or $y-y_1 = m (x-x_1)$ . Substitute $m$ , $x_1$ , and $y_1$ for real values.

Since $m$ represents the slope, substitute 1 for it. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.

$y-1 = 1(x-6)\\y -1 = x-6\\y = x -5$
