Step-by-step explanation:
Answer:
Y=-2X-8
Step-by-step explanation:
m=-2 (X1,Y1)=(-2,0)
(Y-Y1)=M(X-X1)
(Y-(0))=-2(X-(-2))
Y=-2X-8
Reflection across the y axis means multiply the whole function by -1
so
f(x)=3x+12
times -1
g(x)=-3x-12 is the answer
answer is C
not sure why you put an arrow to choice A, but it's wrong
C is the right answer
0.24 should be your answer
Answer:
C
Step-by-step explanation:
Perpendicular lines have the exact opposite slope of the other equation.
So the slope will be x or 1x. Plug in
-8 = 1(4) + b (b represents y-intercept) like y=mx+b
-8 = 4 + b (subtract 4 on both sides)
-12 = b
The equation is y = x - 12
C
solve
y + 8 = x - 4 (subtract 8 on both sides)
y = x - 12
