Given equation is y=3x+3 and 
Let's simplify the 2nd equation
before we can start graph so that calculation will be easy

multiply both sides by 3 to cancel out fractions

y=3x+3
which is exactly same as the first equation so graph of both will be exactly same and solution will be infinitely many solutions.
y=3x+3 has y-intercept 3 so first point will be (0,3). Slope is 3 so rise 3 unit up then 1 right and graph the new point.
The percent of error can be found by dividing the difference in weights by the predicted weight.
290 - 258 = 32 pounds
32/258 = 0.124
0.124 = 12.4% approximately was the percent of error
