sales depends upon advertising.  make your points by (x,y)
from those 2 points do you know the formula for slope

anonymous · Answer

ah thanks...
is that the only formula to be used?

anonymous · Answer

but what is the x point?
the y point?

anonymous · Answer

once you find the slope -
take one of the points and create line by point slope formula

the rest you can figure out

anonymous · Answer

is the spends the the x point and the advertising is the y point?

anonymous · Answer

y depends on x
sales depends on advertising
