The equation of a line perpendicular to the line y = -2 and passing through the point (-6, 2 ) would be:

x = - 6

Step-by-step explanation:

The line with equation y = - 2 is a horizontal line parallel to the x- axis.

The equation of a vertical line and perpendicular to the horizontal line is

x = c

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

The line passes through (- 6, 2) with x- coordinate of - 6, thus

x = - 6 ← equation of perpendicular line

43

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
