Question 312396
They give you one point and slope.  This is all you need to plug into the point-slope formula.

The point-slope formula is: y - a = m(x - b).

If (a,b) represents your point, then a = 1 and b = 1.

If m represents your slope, then m = -3.

We now plug and chug.

y - 1 = -3(x - 1)

y - 1 = -3x + 3

y = -3x + 3 + 1

y = -3x + 4

Done!
