Question 890852
Most of the work is done since you already have the slope. So the slope-intercept formula is y=mx+b. We already know what y, m, and x equals, we just want b (the y-intercept).

The formula looks like this right now: {{{ y=(-3/4)x+b }}}

with the point you've been given: {{{ (-5) = (-3/4)(0)+b }}} this simplifies to -5=b

The final answer is {{{ y=(-3/4)x-5 }}} You can double check this by plotting this line and making sure that the point that you've been given is on the line. 

{{{graph(300,200,-4.5,4.5,-7,7,y=(-3/4)x-5) }}}

By looking at the graph, we can see that it is.
