Question 319171: I'm working with graphing equations and slopes, and I'm stumped:
The instruction is to "graph the specified lines. Draw l1 (the second 1 is a subscript 1) through (-4, 0) and (0, 6). What is the slope of any line parallel to l1 (again, the second 1 is a subscript Draw l2(the 2 is a subscript 2) through the origin and parallel to l1(the second 1 is a subscript)
I have no idea what this question means... please explain?! THanks in advance for your help!

You weren't paying attention in class...

A line that passes through two points and , has a slope given by:



Just plug in the numbers and do the arithmetic.

Parallel lines have identical slopes, that is:





So equation of :





has to go through the origin, so:





The red line is and the green line is
