sorry i got a wrong slope... this is the correct answer... 9x-8y=3 (-8y=-9x+3)/-8 y=9/8x - 3/8 m=9/8 given: m= 9/8 and (6,-7) y-(-7)=9/8(x-6) y+7=9/8x-27/4 y=9/8x-27/4-7 y=9/8x-55/4 final answer...
First, get the slope of the equation by writing it in the form y=mx+b. given: 9x-8y=3 (-8y=-9x+3)/-8 y=8/9x-3/8 slope=8/9 use point-slope form m=8/9 and (6,-7) y-(-7)=8/9(x-6) y+7=8/9x-48/9 y=8/9x-48/9-7 Final answer: y=8/9x - 37/3
