From Greg:
A line is perpendicular to the line y=2x+3 and has the same x-intercept as x+3y+10.
Find the equation of this line. Express your answer in the form of y=mx+b. Justify your answer.

From Hailey:
In the xy-plane,
the line with equation 2x + y = 3
is perpendicular to the line with equation y = mx + b,
where m and b are constants.
What is the value of m?

From C:
Can you help me determine whether these lines are parallel, perpendicular or neither and why?
Problem 1: y=3x+2
y=1/3x - 4
Problem 2: y=1/3x + 1/2
y=1/3 x -2
