Parallel lines l 1 and l 2 have slopes m 1 and m 2 , respectively. Find m 2 if m 1 equals: a) 4 5 b) - 1 5 c) 3 d) f + g h + j

To determine

(a)

To find:

The slope m2 of the line l2, if slope m1 of the line l1 is 45.

Explanation

By theorem,

If two lines are parallel, then their slopes are equal.

(i.e) If l1l2, then m1=m2.

The given lines l1, and l2 are parallel

To determine

(b)

To find:

The slope m2 of the line l2, if slope m1 of the line l1 is -15.

To determine

(c)

To find:

The slope m2 of the line l2, if slope m1 of the line l1 is 3.

To determine

(d)

To find:

The slope m2 of the line l2, if slope m1 of the line l1 is f+gh+j.
