Question

find the line passing through(-2,3)and parallel to x+y+1=0.

Answer 1

Parallel lines have the same slope.

The x-axis is simply a horizontal

line:  y=0

The same as y = 0x + 0

The slope is zero

 

Any parallel line will also have a slope

of zero and be of the form y = c

where c is a number

 

The line passing through (2,-3) parallel

to the x-axis is

 

y = -3
