How to graph y=3x-8
2 answers:
first: put your first point at -8
second: then from the point at -8, go up three times, and over to your right one time
now do that however many times you need to
explanation:
- the y-intercept is the initial value which is -8. the line must pass through -8 so you would start your line at -8
- your slope is 3x. slope is so you rise 3 time and over 1 time
Answer:
The graph of the linear equation is attached below
Step-by-step explanation:
To graph a linear equation , we use a table method
We take some random number for x and find out y. Always assume some positive as well as negative numbers.
x y=3x-8
-1 3(-1)-8= -11
0 3(0)-8=-8
1 3(1)-8= -5
The points for graphing are (-1,-11) (0,-8) and (1,-5)

<u>Probability and Sets</u>
We are given two sets: Students that play basketball and students that play baseball.
It's given there are 29 students in certain Algebra 2 class, 10 of which don't play any of the mentioned sports.
This leaves only 29-10=19 players of either baseball, basketball, or both sports. If one student is randomly selected, then the propability that they play basketball or baseball is:
P = 0.66
Note: if we are to calculate the probability to choose one student who plays only one of the sports, then we proceed as follows:
We also know 7 students play basketball and 14 play baseball. Since 14+7 =21, the difference of 21-19=2 students corresponds to those who play both sports.
Thus, there 19-2=17 students who play only one of the sports. The probability is:
P = 0.59
