Let's start with point slope form of the equation:
y - k = m(x - h)
So first we need the slope, which is the difference in the "y"s over the differences in the "x"s:
(-1 - 4) / (2 - 5)
-5 / (-3)
5/3
So that's your slope, m. Pick a point and use the values to fill in (h, k). I'll use the first point, so now we have:
y + 1 = (5/3)(x - 2)
Now we want it in general form, which is:
ax + by = c
Where b and c are integers and a is a positive integer. So I'll start with multiplying both halves by 3 (the denominator of the slope) and then simplifying:
3y + 3 = 5(x - 2)
3y + 3 = 5x - 10
-5x + 3y = -13
Since we want the coefficient of "x" to be positive, multiply both halves by -1:
5x - 3y = 13
That's the answer to your question. Best Answer if this helped.
