SInce it passes thru the origin, the y intercept is zero, so you need only find the slope. The point is (-5,3) so change in y / change in x is 3/(-5). So the equation is y = (-3/5)x.

if it passes through the origin
in y=ax+b b=0
so y = ax
replace x by -5 and y by 3
you get 3 = -5a so a= -3/5 and y=(-3 /5)x

y=mx+b
Since line passes through origin, b=0
So y= mx
So 3= m(-5)
m= -3/5 =- 0.6
In your case , k= -0.6

y=kx
3=-5k
k=-3/5
y=-3x/5
