Answer

Refer to the image below for the graph.

Work Step by Step

The given line has a slope of -2 and a y-intercept of 4. To graph the given line using the slope and y-intercept, perform the following steps: (1) Plot the y-intercept point $(0, 4)$. (2) From $(0, 4)$, move 2 units down (the rise) and move 1 unit to the right (the run). These moves lead to the point $(1, 2)$. (3) Connect $(0, 4)$ and $(1, 2)$ using a line. (Please refer to the attached image in the answer part above for the graph.)
