It is given that Roberts father is 5 years older than 3 times Robert's age which means that Roberts Father's age is 5 years more than 3 times the age of Roberts
∴ Roberts Father's age is: 3 times of Robert age + 5 years
B is correct. Explanation Below: --- Line A never intersects Line B, as they are parallel lines-the slopes are the same-and parallel lines never intersect. Line A's Slope: (9-5)/(-1-1) = -2 Line B's Slope: (-6-2)/(4-0) = -2 --- Hope this helps!
