Question

Parallel and Perpendicular Lines
Fill the blanks
1. If slope of line is 3 a line parallel to this line has slope ----
2. If slope of line is 4/3 a line perpendicular to this line has slope ...
3. If slope of line is - 6/7 a line perpendicular to this line has slope
4. If the equations of given lines are y =3x +6
Y = 3x -7 the lines are​

Answer 1

Answer:

1. For parallel lines, slopes are equal,m1 = m2.

• 3

2. For perpendicular lines,products of slope of respective lines give product - 1. m1m2 = - 1

• -3/4

3. 7/6

4. Comparing y = mx + c1 and y = mx + c2.. Since, slope 'm' is equal for both lines. So, they will be parallel.
