Answer
(a) slope-intercept form: $y = -2x$
(b) slope = $-2$, y-intercept = $0$
(c) Refer to the image below for the graph.
Work Step by Step
a) The slope-intercept form is $y=mx+b$ where m = slope and b = y-intercept.
Subtract $2x$ on both sides to obtain:
$y = -2x$
(b) The equation has $m=-2$ and $b=0$.
Thus, slope = $-2$, and y-intercept = $0$.
(c) Plot the y-intercept point $(0, 0)$.
From $(0, 0)$, move 2 units down (the rise) and 1 unit to the right (the run).
These steps lead to the point $(1, -2)$.
Connect the two points using a line to complete the graph.
