Question
In Exercises $11-42,$ solve each system by graphing. If there is no solution or an infinite number of solutions, so state. Use set notation to express solution sets.$$\left\{\begin{array}{l}y=2 x-1 \\x-2 y=-4\end{array}\right.$$
Step 1
This equation is in slope-intercept form, so we know that the slope is $2$ and the y-intercept is $-1$. We plot the y-intercept at $-1$ on the y-axis and then draw a line with a slope of $2$. Show more…
