Answer:

Option a)  y = - 4x + 3 is the correct answer

Step-by-step explanation:

Marked co-ordinates of given line are (0,3) and (2,-5)

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

              = -5-3 / 2-0

              = -8/2

              = -4

Equation of straight line

y = mx + c

Equation

3 = -4(0) + c

3 = 0 + c

c = 3

y = -4x + 3

A)

y + 5 = -4( x - 2)

   y = -4x + 8 - 5

   y = - 4x + 3

The point slope equation of the line is  y + 5 = -4( x - 2)
