Answer:
y - 3 = -2(x - 1)
Step-by-step explanation:
Let's find the slope of the line first. Going from (1, 3) to (4, -3), x (the "run") increases by 3 and y (the "rise") decreases by 6 . Thus, the slope is
m = rise/run = -6/3 = -2.
To find the point-slope equation, we can use either given point, (1, 3) or (4, -3). Using the first one,
y - 3 = -2(x - 1)
This matches the first of the four answer choices.
