Answer:
y = 1 , y = x
Step-by-step explanation:
Consider the line with points (0,1) and (2,1)
Slope of a straight line = change in y ÷ change in x
Slope of this line = [tex]\frac{1 - 1}{2 - 0}[/tex] = 0
Taking another point (x,y) on the line;
Slope = [tex]\frac{y - 1}{x - 2}[/tex] = 0
y - 1 = (x - 2)0
y = 1 (and this is the equation of the line)
Consider the line which passes through points (-1,-1) and (0,0)
Slope = [tex]\frac{0 - - 1}{0 - - 1}[/tex] = 1
Taking another point (x,y) on the line;
slope = [tex]\frac{y - 0}{x - 0}[/tex] = 1
y = x (and this is the equation of our second line)
