See explanation below

The given equation of straight line:

$5x+y=4$

The above line intersects the x-axis where $y=0$ hence

$5x+0=4$

$x=4/5$

hence the point of intersection of line with the x-axis is $(4/5, 0)$

Similarly, the above line intersects the y-axis where $x=0$ hence

$5(0)+y=4$

$y=4$

hence the point of intersection of line with the x-axis is $(0, 4)$

Now, specify both the intersection points $(4/5, 0)$ & $(0, 4)$ on x & y axes then join them by a straight line to get desired graph
