Question

Find three solutions of 9x – 2y = 18
(0, 0), (9, 2), (2, 9)
(0, –2), (9, 0), (9, –2)
(0, 2), (–9, 0), (1, 7)
(0, –9), (2, 0), (1, –4.5)

Answer 1

inserting the values (x,0) in the equation you get
9x-0=18
x=18/9=2 so (2,0) will be one solution

inserting the values (0,y) in the equation you get
0-2y=18
y= -18/2= -9
so (0,-9) will be another solution

now assume x=1 and find the value of y
9*1-2y=18
-2y=18-9
-2y=9
y= -9/2
y= -4.5
so (0,- 4.5) would be one solution
(0, -9), (2, 0), (1, -4.5) is the correct option

Answer 2
