Answer:
x = 1, y = 3
Step-by-step explanation:
x = y - 2, so y = 4 (y - 2) -1
solve normally now
y = 4 (y - 2) -1
y = 4y - 8 - 1 (distribute)
y = 4y - 9 (simplify)
+9 -y -y +9
9 = 3y
3 = y
y - 2 = x
(3) - 2 = x
x = 1
Answer:
y= -2x+1
Step-by-step explanation:
y=mx+b
Substitute the ordered pairs into the equation
So:
y= -1 m(slope) = -2 x=1 b=?
-1 = (-2)(1) + b
-1 = -2 +b add 2 on both sides to get b by itself
-1 +2 = b
b=1
Answer:
d
Step-by-step explanation:
took da test
Parallel, therefore gradient is the same = 2
y-y1=m(x-x1)
y+2=2(x-3)
y+2=2x-6
y=2x-8
