What is the least common multiple of 2, 10 and 15?

Step-by-step explanation:

2 = 1 x 2

10 = 2 x 5

15 = 3 x 5

LCM (2,10,15) = 1 x 2 x 3 x 5 =

2 x 3 x 5 =

6 x 5 =

30

Hope that helps!

y = 2

Step-by-step explanation:

x = - 3 is the equation of a vertical line parallel to the y- axis.

Thus a perpendicular line must be a horizontal line parallel to the x- axis with equation

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (- 4, 2) with y- coordinate 2, thus

y = 2 ← equation of perpendicular line
