Answer

$(-3,-11)$

Work Step by Step

$1$. First equation $y=4x+1$.The slope is $m=4$ and the y-intercept is $b=1$.Graph the first equation on a graph (blue line) $2.$ The second equation is $y=2x-5$.The slope is $m=2$ and the y-intercept is $b=-5$. Graph the second equation (red line) $3.$ The two equations intersect at $(-3,-11)$ so that's the solution.
