Question

Equation C: y = 6x + 9
Equation D: y = 6x + 2

Which of the following options is true about the solution to the given set of equations?

One solution
No solution
Two solutions
Infinite solutions

Answer 1

y = mx + b, where
m = slope and b = y-intercept

You have two equations with the same slope. m = slope = 6 for both.
The slope tells you what the inclination or tilt of the line is.
These two lines have the same inclination. That means they are either the same line or parallel lines.

The y-intercept tells you where the lines cross the y-axis.
Here the y-intercepts are 9 and 2. Since the y-intercepts are different, the lines are different lines but parallel.
