7x+5y=10
5y= -7x +10
y=  -7/5x +2      to get the y intercept, let x = 0
 thus    y  intercept = 2
                         to find the x intercept, let  y = 0
thus    x  intercept  =  2/(7/5) =  10/7
the slope is    -7/10     &    the trend of the line is decreasing
                                           from left to right
