Answer:
option A:
y = -4/9x
Explanation:
the equation of the line is, y = mx + c
the given two co-ordinates of the line are,
x1, y1 = 0, 0
x2, y2 = 9, -4
slope, m = y2 - y1 / x2 - x1
= -4 - 0 / 9 - 0 = -4/9
to find the value of constant c, let's take any (x, y) co-ordinates
i am taking x1, y1 = 0, 0
0 = -4/9(0) + c
c = 0
thus, by substituting the values the equation of the line is,
y = -4/9x + 0
y = -4/9x
