Answer
slope = -1
y-intercept = 3
Refer to attached image for the graph.
Work Step by Step
RECALL:
(i)
The slope-intercept form a line’s equation is $y=mx+b$ where m=slope and $b$=y-intercept.
(ii)
slope = $\frac{\text{rise}}{\text{run}}$
Write the given equation in slope-intercept form to have:
$\\y= -x+3$
This equation has m=-1 and b=3.
Thus, the slope of the line is $-1$ and the y-intercept is 3.
Plot the y-intercept point (0, 3).
The slope is -1 so from (0 , 3), move 1 unit upward then 1 unit to the left to end at (-1, 4).
Complete the graph by connecting the two points using a line.
