Let us substitute different values for x in the linear equation y = 3x + 5
x → 0, 1, 2, ..., 100
y, where y = 3x + 5 → 5, 8, 11, ..., 305
From the table, it is clear that x can have infinite values, and for all the infinite values of x, there are infinite values of y as well.
Hence, (iii) infinitely many solutions is the only option true.
