b=51/2 so 3=45/2 + b add 45/2 to both sides and change 3 to 6/2 so you can add 45/2 y=9/2 x +51/2

4x+3y=7 solve for y 4x 4x 3y=74x or 3y=4x+7  3 y=4/3 x + 7/3 so slope is 4/3 parallel lines have same slope so use m=4/3 and (5, 5) and plug into slopeintercept form to find "b"y intercept y=mx+b 5=4/3(5)+b 5=20/3 + b +20/3 +20/3 15/3 + 20/3 = b 5/3= b so y=4/3x + 5/3
