Find the x and y intercepts and graph 9x + 8y = 72. Graph the points.

y intercept is when x is zero.
9*0+8y=72 what is y?
x intercept is when y is zero,
9x+8*0=72 what is x? 
give the slope of each line then determine whether the two lines are paralell, perpendicular, or neither.
slope of 4x+5y=5, 15x+12y=0 
HORIZONTAL LINE X  Y
