What's the equation of the line with a slope of -3 (m=-3) that passes through (-1,2)

You can use slop point form: y-y1=m(x-x1)

y-2=-3(x+1)
y-2=-3x-3
y=-3x-1

Hope this helps!

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
