Question

Express y is the terms of x and check weather the point (-3,-2) lies on the line or not 3x-2y+5=0​

Answer 1

$\mathbb\red{Solution:-}$

$\rightarrow2y = 8 - 3x$

$\rightarrow y = \frac{8 - 3x}{2}$

$\rightarrow \: For \: pr.( 4,-2)$

$\rightarrow 3×4+2×(-2)$

$\rightarrow 12 +4 = 8$

$\rightarrow 8 = 8$

$\rightarrow LHS = RHS$

$\therefore ( 4,-2) \: lies \: on \: the \: \: line.$
