Answer:
-x-y=0 is not the equation of the line
Step-by-step explanation:
Lets find equation of a line that passes through points (1, 1) and (5, 5)
Slope = [tex]\frac{y2-y1}{x2-x1} =\frac{5-1}{5-1} =1[/tex]
Slope = 1 and use point (1,1)
y-y1= m(x-x1)
y-1= 1(x-1)
y-1 = x-1
add 1 on both sides
y=x
when we subtract x on both sides then equation becomes y-x=0
when we subtract y on both sides then equation becomes x-y=0
so -x-y=0 is not the equation of the line
