To determine which among the given choices best fit as the description of the equations of the line, we determine the relationship between their slopes. In a slope-intercept form of the line such as,
y = mx + b
m is the slope.
The value of the slope of the first equation is -3 and that of the second equation is also -3. Then, we look into their y-intercept, b.
The y-intercept ofhte first equation is 1 and that of the second equation is also 1. Since both lines have the same slope and y-intercept, they are said to be COINCIDENT.
