Question
Without graphing, decide whether each system has one solution, infinitely many solutions, or no solution. Justify your answer.$$\begin{array}{l}{y=x-4} \\ {y=x-3}\end{array}$$
Step 1
The slope of a linear equation in the form $y = mx + b$ is $m$. For the first equation, $y = x - 4$, the slope is 1. For the second equation, $y = x - 3$, the slope is also 1. Show more…
