Answer: y = 1/2 or y = -1/2
Step-by-step explanation:
First move the 1 to the side with the 0
-4y^2 = -1 // -1 because when you move a number to the other side of the equation you have to multiply -1
Then divide by -4 on each side
y^2 = 1/4
square root each side
|y| = 1/2 // sq rt y^2 becomes an absolute value because when you square root a square it automatically becomes an absolute value
so the answer would be y = 1/2 or -1/2
to check just put it into the equation as y. Both work.

Answer:
y = 4/3
Step-by-step explanation:
For an eqtuaion wih slope m and goes through point (x1,y1)
equation is
y-y1=m(x-x1)
so
point (-1,6)
slope=-3
y-6=-3(x-(-1))
y-6=-3(x+1)
