Answer:

Line p

Explanation:

If a line slopes up to the right, it has a positive slope.

Line n and p slope up to the right, so they have positive slopes.

If a line slopes down to the right, it has a negative slope.

Lines l and m slope down to the right, so they have negative slopes.

Eliminate lines l and m.

The answer is either line n or line p.

slope = rise/run

rise is vertical distance (parallel to the y-axis)

run is horizontal distance (parallel to the x-axis)

Let's try line n:

Look at the two points marked on line n.

Start at the lower pouint. Go up vertically 6 units. Then go right 2 units.

rise = 6; run = 2

slope = rise/run = 6/2 = 3

The slope of line n is 3.

Now we do the same for line p.

Look at the two points marked on line p.

Start at the lower pouint. Go up vertically 7 units. Then go right 1 unit.

rise = 7; run = 1

slope = rise/run = 7/1 = 7

The slope of line n is 7.

Answer: Line p
