multiple choice 2 points
if a fair coin is tossed four times, the probability of getting exactly three heads is
multiple choice 2 points
which is the equation of a line whose slope is -2 and whose y - intercept is 3?
$y = 3x - 2$
$y = 2x - 3$
$y = - 2x + 3$
$y = 3x + 2$

Explanation:

Step1: Recall the slope - intercept form of a line

The slope - intercept form of a line is \(y = mx + b\), where \(m\) is the slope and \(b\) is the \(y\) - intercept.

Step2: Substitute the given values of slope and \(y\) - intercept

Given \(m=-2\) and \(b = 3\). Substituting these values into the slope - intercept form \(y=mx + b\), we get \(y=-2x + 3\).

Answer:

\(y=-2x + 3\)
