Someone help me with finding an x and y equation and then finding points and graphing them (btw srry for my horrible computer writing skills its just so terrible)

main (79,1580) when start graphing start with (1,20)

Step-by-step explanation:

(x,y)

x is number of students which is 79 and

y is  the cost which is 1580

so the  answer is  (79,1580)

79 students cost 1580

1 student cost 1580/79=20 $

so start with

(1,20)

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300
