I need help now. How would i do it if I knew the slope. and two points? say the slope is -3 and the points were (-3,3) DETAILS PLEASE!

if you have the slope and a point you can use the point slope formula to get the slope-intercept equation.
y-y1=m(x-x1)
y-3=-3(x+3)
y-3= -3x-9
y=-3x-12
to get standard form you just move the x and y to the same side.
3x+y= -12
y-y1=m(x-x1)
y-3=-3(x+3)
y-3= -3x-9
y=-3x-12
to get standard form you just move the x and y to the same side.
3x+y= -12
