Answer:
Answer B - y=[x]+7
Step-by-step explanation:
A normal [x] function has a slope of one, a y intercept of 0, and all the other basic values.
7 changes this.
Looking at the graph, we see that the y intercept is now 7.
How can this be? x was added to by 7.
If it was subtracted, it would be -7, not postive 7.
So the answer is y=[x]+7

Answer:
Step-by-step explanation:
Slope-intercept form is given as 
, where 
is slope and 
is the y-intercept.
To find the slope of a line that passes through two points 
and 
, use the slope formula:
Let:
The slope of the line that passes through these two points is:
Now substitute 
and any point to solve for :
Therefore, the slope-intercept form of a line that is represented by the table is 
Answer:
1) biased sample
2) random sampling
Step-by-step explanation:
Since the results are based on feedback of students in only one class, it's not a good representative of the entire student body.
Also, since it's a math class there will be a bias.
Better method would be randomly selecting students from the entire school students list and take their feedback
