Work Step by Step

RECALL: The slope-intercept form of a line's equation is $y=mx+b$ where $m$=slope and $(0, b)$ is the line's y-intercept. The given equation has a slope of $2$ and a y-intercept of $(0, -1)$ Plot the y-intercept $(0, -1)$. Then, use the slope to plot a second point. From $(0, -1)$, move 2 units up (the rise) and 1 unit to the right (the run) to reach $(1, 1)$. Plot $(1, 1)$. Connect the two points using a line to complete the graph. (Refer to the graph in the answer part above.)
