<PRE><B>Question 68474</B>
Write the equation of the line with slope -2 and y intercept(0,0)
Then graph the line
:
The slope intercept form of a line is {{{highlight(y=mx+b)}}}, where m=slope and (0,b)=y-intercept.
m=-2 and (0,b)=(0,0)
{{{y=(-2)x+(0)}}}
{{{y=-2x+0}}}
{{{highlight(y=-2x)}}}
To graph this line, plot a point at the y-intercept (0,0)
From that point use the slope m=rise/run to plot another point.  Think of m=-2 as m=-2/1, go down 2 and right 1 and plot another point at (1,-2).  Connect the two points and you should have a line that looks like:
{{{graph(300,200,-10,10,-10,10,-2x)}}}
