Identify the points which lie on the line 3x + 4y = 7.
3x - 2y = 5
2x + y = 17
x - 2y = 4
If a point lies on a line, the coordinates should satisfy the equation of the line. So any point lying on the line 3x + 4y = 7 is a solution.
Let's substitute the points given in the options in 3x + 4y = 7 to check which of them satisfy the equation.
(1,1):
3x+4y=7⇒3×(1)+4×(1)=7=RHS
(0,74):
3x+4y=7⇒3×(0)+4×(74)=7=RHS
(0,7):
3x+4y=7⇒3×(0)+4×(7)=28≠RHS
(73,0):
3x+4y=7⇒3×(73)+4×(0)=7=RHS
