write equations for the vertical and horizontal lines passing through the point (-6, -5)

see below

Step-by-step explanation:

A horizontal line has the same y value and is a constant y value

y = -5

A vertical line has the same x value and is a constant x value

x = -6

A vertical line is a line where all of the values are the same. In this case, , so that is the equation of the line.

A horizontal line is a line where all of the values are the same.  Here, , so that is the second line.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
