In order to graph this equation, we only need two points to create a straight line


So let's pick simple values to plug into x


y+=+%286%2F5%29x-4 Start with the given equation


y+=+%286%2F5%29%280%29-4 Plug in x=0 (you can start with any number, but zero is the easiest number to work with)


y+=+0-4 Multiply


y+=+-4 Subtract


So when x=0, the value of y is y=-4. This means we have the first point (0,-4)



-------------Now let's find another point------------



y+=+%286%2F5%29x-4 Start with the given equation


y+=+%286%2F5%29%285%29-4 Plug in x=5 (since the denominator is 5, choosing the value of 5 makes the fraction go away)


y+=+30%2F5-4 Multiply


y+=+6-4 Reduce

y+=+2 Subtract


So when x=5, the value of y is y=2. This means we have the second point (5,2)




So we have the two points (0,-4) and (5,2)



Now plot these two points on a coordinate system





Now draw a straight line through them. This line is the graph of y+=+%286%2F5%29x-4
