For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes, so we can find the slope:
Thus, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is of the form:

Answer: 33 students wore blue jeans .
Step-by-step explanation:
Let x be the number of black pants.
Given : For the choir concert, the choir director has asked that everyone wear either black pants or blue jeans.
Three times as many students wore black pants as blue jeans.
i.e. Number of blue pants = 4x
If there are forty-four students in the choir, then we have
Divide both sides by 4 , we get
Thus , the number of black pants = 11
Then , the number of blue pants =
Therefore, 33 students wore blue jeans .
