Answer
true
Work Step by Step
A point is on a line if its coordinates satisfy the equation of the line.
Substitute the x and y values of the point into the line's equation to obtain:
$2x+y=4
\\2(1) +2 = 4
\\2+2=4
\\4=4$
Since the x and y values of the point satisfy the equation of the line, the point is on the line.
Thus, the given statement is true.
