How many solutions does this system have?
-6x + 18y = 264
-12x - 36y= 130

depends are you using elimination or substitution

Step-by-step explanation:

if elimination then 2 ways

if substitution then 2 ways as well

if all then 4 ways

ir if you mean substitution and elimination then 2

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
