Question 316094
I'm assuming that you meant to write  {{{f(x)=-8x-2}}}. This can be written as {{{y=-8x-2}}} since 'y' and 'f(x)' are really one in the same in this case.



Notice how {{{y=-8x-2}}} is in slope-intercept form {{{y=mx+b}}} where m is the slope and b is the y-intercept.



So this shows us that the slope is {{{m=-8}}} and the y-intercept is {{{b=-2}}}. The y-intercept is the point (-2,0).



That's all there is to it.
