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.
