Answer:
y - 3 = -3(x - 1)
Step-by-step explanation:
The point-slope form is y - k = m(x - h), where (h,k) is a point on the line. Using the given info, replace x with 0, y with 6, h with 1 and k with 3. Then:
6 - 3 = m (0 - 1), or 3 = -m, or m = -3. The slope is 3. Then we have the equation
y - 3 = -3(x - 1).
Check: Does this pass thru (1,3)? Is 3 - 3 = -3(1 - 1) true? Yes, it is.
