The answer depends on the sign preceding the value 15 (which is not given in the question).
If y = -2x+15 then (0,15)
if y= -2x-15 then (0,-15)
11
It is: 5
It would be perpendicular to a line with the equation Y = 1/8 X.
8 lol :]
The slope is 5.
Without the inclusion of an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation
2.3
11
9
It is: 5
It would be perpendicular to a line with the equation Y = 1/8 X.
The slope of the graph of that equation is -1.
8 lol :]
Slope = 3
Well, to answer your question,
the slope is -1/3
The slope is 5.
