Question 412824
6x+5y=2                 and 3x+2.5y=-7
re write in slope intercept form y=mx+b

5y=-6x+2
y =(-6/5)x+2/5= -1.2 x+ .4

2nd eq is 2.5y=-3x-7
             y= (-3/2.5)x-7/2.5
             y= -1.2 x- 2.8
            for parallel lines slope hase to be same so intercept will be diff.
Plot both lines
