Answer

$(1,-2)$

Work Step by Step

The given system of linear equation is $y=-5x+3$ ...... (1) $y=2x-4$ ...... (2) Graph each equation. The intersection point is $(1,-2)$. Check the intersection point. Equation 1: $\Rightarrow y=-5x+3$ $\Rightarrow -2=-5(1)+3$ $\Rightarrow -2=-5+3$ $\Rightarrow -2=-2$ True. Equation 2: $\Rightarrow y=2x-4$ $\Rightarrow -2=2(1)-4$ $\Rightarrow -2=2-4$ $\Rightarrow -2=-2$ True. The solution is $(1,-2)$.
