Graphing this is easier than you think, the equation is already in slope intercept form,
when you start graphing your first gonna try and find the y intercept (b)
![f(x) = m(x) + b](https://tex.z-dn.net/?f=f%28x%29%20%3D%20m%28x%29%20%2B%20b)
lets take excersise 17 for example,
y-intercept is -4, now go to your graph and place the first dot over -4, after that you find the slope, in the equation the slope is m(x) in this case it's 1/2, since its a fraction here's what you do,
Start of from your y-intercept (-4) them if the slope is a fraction you will go from -4 up or down( if the numerator is positive you move upwards, if it's negative you move down words), then from there you love left or right(if the denominater is positive you move right, if it's negative you move left, then draw a line from the y-intercept to the las dot you moved.
The probability that the card is not yellow is ![\frac{5}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B9%7D)
<em><u>Solution:</u></em>
<em><u>The probability of an event is given as:</u></em>
![Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B%20%5Ctext%7B%20number%20of%20favorable%20outcomes%20%7D%7D%7B%20%5Ctext%7B%20total%20number%20of%20possible%20outcomes%20%7D%7D)
From given,
A box is filled with 8 blue cards, 8 yellow cards, and 2 green cards
Total number of possible outcomes = 8 + 8 + 2 = 18
Favorable outcome = card is not yellow
Favorable outcome = card is blue or green = 8 + 2 = 10
Therefore,
![Probability = \frac{10}{18}\\\\Probability = \frac{5}{9}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B10%7D%7B18%7D%5C%5C%5C%5CProbability%20%3D%20%5Cfrac%7B5%7D%7B9%7D)
Thus the probability that the card is not yellow is 5/9
A - 4
B - 10
looking for the LCM (least common multiple)
4 and 10 can both be divided evenly into 20
20 = LCM
