Answer:

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

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)
