wood be nies if yu sae yu need tu find a strate line per equashun:

7x+9y=8 & go thru point=(5,-4)

7x+9y=8, 9y=-7x+8, y=-(7/9) +(8/9)...impli slope=-(7/9)

projekt line from x=5 tu x=0...deltax=-5, deltay=slope*deltax=-5*(-7/9)

deltay=+35/9=3.88888888888888...

so y at x=0 is 8+3.88888...=11.88888888...

formula: y=-(7/9)x +11.8888888888
