Answer:
The slopes of the lines are different.
Explanation:
If you do convert the standard form equation to slope-intercept form, you get ...
y = -x +5
You see that the slope of this line is -1, whereas the slope of the other line is +1. Both lines have a y-intercept of 5. It is the slopes that are different.
_____
You can determine this to be the case without converting the form of the equation if you have some practice with the various forms of the equation of a line.
In standard form, if the variable signs are the same, the slope is negative. Of course, in slope-intercept form, the sign of the slope is the sign of the coefficient of x.
