Answer:
y=10x+75
Step-by-step explanation:

Plug in the y1(5) and x1(-7)
So, y-5 = 10(x+7)
= y=10x+75
One possible equation would be 20 = 1/2x + 4.
Let x be the number of students in his homeroom. 1/2x is half of the students in his homeroom. Four more than 1/2 would be 1/2x + 4. This is, or equals, the 20 students that have tickets.
