Answer» Step-by-step EXPLANATION: The given EQUATIONS are 3x-y=23x−y=2 2x-y=32x−y=3 Substitute x=0, to find the y-intercepts. 3(0)-y=2\Rightarrow y=-23(0)−y=2⇒y=−2 2(0)-y=3\Rightarrow y=-32(0)−y=3⇒y=−3 The y-intercept of lines at (0,-2) and (0,-3) respectively. Substitute y=0, to find the x-intercepts. 3x-(0)=2\Rightarrow x=\frac{2}{3}3x−(0)=2⇒x= 3 2
2x-(0)=3\Rightarrow x=1.52x−(0)=3⇒x=1.5 |
