The answer would be 0.45 feet because you have to take the 6 and subtract 5.55 feet from it. Your equation would be x+5.55=6.
8 times 3 = 24 +4= 28
4+3=7 times 8 =56
the slope intercept form is y=mx+b
since the line intersects at (0,3) b= 3
since the slope is 0 m= 0
so the equation would be y=0x+3 or y=3
