Question 66637
Write the equation of the line with slope -2 and y-intercept (0,0). Then graph the line. The equations I have are:
a)y = -2x
b) y = -2x
c)y = x - 2
d)y = x-2

The slope intercept form of a line is, {{{highlight(y=mx+b)}}}, where m=slope and (0,b)=y-intercept
Your m=-2 and (0,b)=(0,0)
{{{y=-2x+0}}}
{{{highlight(y=-2x)}}} that's (a) and (b) on your multiple choices. 
(Why are a and b the same? Why are c and d the same?)
Happy Calculating!!!
