The equation of the line is
Explanation:
Given that the set of ordered pairs is (0,0), (2,1), (4,2), (6,3)
We need to determine the equation of the line.
<u>Slope:</u>
The slope of the line can be determined using the formula,
Let us substitute any two coordinates in the formula.
Thus, substituting the coordinates (2,1) and (6,3) in the above formula, we have,
Thus, the slope of the line is
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Let us substitute any one of the coordinates and the slope in the above formula.
Hence, substituting and the coordinate (0,0), we get,
Hence, the equation of the line is
The probability of either a yellow or a red ball being drawn if only one is drawn is 7/16.
<h3>What is probability?</h3>The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event. The formula for probability is given by; P(E) = Number of Favourable Outcomes/Number of total outcomes.
According to the given question.
Numnber of yellow balls = 2
Number of green balls = 3
Number of red balls = 5
Number of black balls = 6
So,
The total number of balls in a bag = 2+ 3+ 5 + 6 = 16
And,
The sum of yellow and red ball = 2 + 5 = 7
Therefore,
The probability of either a yellow or a red ball being drawn if only one ball is drawn
=
Hence, the probability of either a yellow or a red ball being drawn if only one is drawn is 7/16.
