Answer:
same for both ; slope = -8 and y-intercept is (0, -3)
Explanation:
First, lets write both of these in slope-intercept form!
-8x-y=3 is the same as -y = 8x+3, which is the same as y = -8x-3.
8x+y=-3 is the same as y = -8x-3.
As you can see, these equations are the same, which means that they have the same slopes and y-intercepts.
Since the equation for slope intercept form is y= mx + b where m is the slope and b is the y-intercept, this means that the slope is -8 and the y-intercept is (0, -3).
