Work Step by Step
Written in slope-intercept form, $y=mx+b$
$y=-2x+6$
The y-intercept is b=$6$,
the line passes through (0,$6$).
One more point needed (two points determine a line).
When x=1,
y=$-2(1)+6=4$
So, another point on the line is (1,$4$).
Plot the two points and draw a straight line through them.
