Find the number of solutions to a system of equations

Full solution

Q. How many solutions does the system of equations below have?

\newline

y = -3x - 7

\newline

y = -3x - 7

\newline

Choices:

\newline

(A)no solution

\newline

(B)one solution

\newline

(C)infinitely many solutions

Slope Comparison: System of equations: $\newline$ $y = -3x - 7$ $\newline$ $y = -3x - 7$ $\newline$ Are the slopes same or different? $\newline$ Slope of first equation: $-3$ $\newline$ Slope of second equation: $-3$ $\newline$ Slopes of the equations are the same.
Y-Intercept Comparison: System of equations: $\newline$ $y = -3x - 7$ $\newline$ $y = -3x - 7$ $\newline$ Are the y-intercepts same or different? $\newline$ y-intercept of first equation: $-7$ $\newline$ y-intercept of second equation: $-7$ $\newline$ y-intercepts of the equations are the same.
Number of Solutions: System of equations: $\newline$ $y = -3x - 7$ $\newline$ $y = -3x - 7$ $\newline$ Determine the number of solutions to the system of equations. $\newline$ The system of equations has the same slope and the same $y$ -intercept. $\newline$ The system of equations has infinitely many solutions.
