match each equation with the description of it's graph below .

We have the following:
[tex]y=-10x[/tex]My graph has a negative slope and passes throgh the origin.
[tex]y=2.5x-7[/tex]My graphic increases form left to right, and my "b" value is negative
[tex]x=\frac{7}{8}x+1[/tex]My graph is non-proportional with positive y-intercept
[tex]y=1.2x[/tex]My grahp contains the point (0,0) and has a positive slope
[tex]y=-5x-8[/tex]My graph has a negative "m" value and a negative "b" value
