Given below are descriptions of two lines. Line 1: Goes through (-2,10) and (1,1) Line 2: Goes through (-2,8) and (2,-4)

Option (2)

Step-by-step explanation:

1). If two lines have the same slope, lines are defined as parallel.

m₁ = m₂

2). If the multiplication of the slopes of two lines is (-1), lines will be perpendicular.

m₁ × m₂ = (-1)

Line 1 : It passes through two points (-2, 10) and (1, 1).

Slope of the line 1 =

                              =

                              =

                         m₁ =

Line 2 : It passes through two points (-2, 8) and (2, -4).

Slope of the line 2 =

                               =

                               =

                         m₂ = -3

Since, m₁ × m₂ =

                        = (-1)

Therefore, given lines are perpendicular to each other.

Option (2) is the correct option.

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
