Linear Relationships, SM-Bank 059 Verify that the points \((1\ ,\ -1)\) and \((-7 ,\ 3)\) lie on the line \(x+2y=-1\)? (3 marks) --- 6 WORK AREA LINES (style=lined) --- Show Answers Only \(\text{See worked solution}\) Show Worked Solution \(\text{Check points by substituting into }x+2y=-1\) \((1\ ,-1) \longrightarrow\) \(LHS\) \(=1+2\times (-1)\) \(=1-2=-1\) \(=RHS\) \((-7 ,\ 3) \longrightarrow\) \(LHS\) \(=-7+2\times 3\) \(=-7+6=-1\) \(=RHS\) \(\therefore\ (1\ ,-1)\ \text{and }(-7 ,\ 3) \text{ both lie on the line}\ \ x+2y=-1\)
