Solve the system by graphing. 2x-2y=5 y=x-4

Convert 2x-2y=5 into y=mx+b
-2y=-2x+5
Divide all by -2 to get the Y-intercept and Slope.
y = x-2.5
The slope is 1, and the Y-Intercept is -2.5

y=x-4 is already in y=mx+b, so just graph this one.
The slope is 1, Y-Intercept is -4.
The graphs are listed in the picture.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
