Since we already have X, I'm guessing all the question asks you to do is plug it in and solve it to get a Y= equation
If I'm right, then the process is
Y=2(3)+1 (putting 3 in place of x)
Y=6+1
Y=7
Which makes 7 your answer
a)All points on one line are at the same Collinear points to the other line.
b)The distance between the two lines is called the perpendicular lines.
Triangle BCG or d I'm pretty sure . Hope I'm right :)
