It's a straight line with slope = 2/4 = 1/2
y = (2/4)x -5 is the same as
y= (1/2)x -5 which is in slope intercept form, with slope = 1/2 and y intercept = -5 or the point (0,-5)
the x intercept is found by setting y=0 and solve for x
0 =(1/2)x -5
x =10 or the point (10,0)
0=(1/2)(10) -5
0=5-5
plot the 2 intercepts (0,-5) and (10,0). connect them with a straight line, extend the line beyond that line segment into quadrants I and III, and put an arrow at both ends indicating the line goes forever in both directions. That's the graph of the equation.
