Question

find the equation of the line that passes through the point (-1, 0) and(-4, 12)​

Answer 1

Step-by-step explanation:

given points P (-1, 0) and Q (-4, 12)

to find the equation of line passing through these two points

y - y1 = m (x - x1)

x1 = -1, y1 = 0, x2 = - 4 , y2 = 12

m = (y2 - y1) / (x2 - x1)

m = (12 - 0) ) (- 4 -(-1)) => - 12 / 3 => - 4

y - 0 = - 4 [x - (-1)]

y = - 4 (x + 1)

y = - 4x - 4

4x - y + 4 = 0
