Answer:
(2,-4)
Step-by-step explanation:
When a point (x,y) is reflected across the y-axis, you need to change the sign of x. For example, if (-x,y) you need to take away the negative sign, which makes (x,y). Or, if the point is (x,y), you need to add a negative sign to the x, which makes (-x,y). So, if your point (-2, -4) is reflected across the y-axis, you need to take the negative sign off the -2, which makes (2,-4).
3/4 w = 9
multiply by 4/3 on both sides
4/3 x 3/4 w = 9 x 4/3
w = 9 x 4/3
Simplify that
w = 3 x 4
w = 12
So your final answer is
Answer:

Step-by-step explanation:
Slope intercept formula is y=mx+b
(m) is slope
(b) is the y intercept
We'll find slope first.
slope formula is

y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.
So we just put the given values into our equation.

Simplify

Now we put this into our y=mx+b
y=0/-3x+b
now we need the (b)
to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.


Solve
1=0+b
b=1
Put this in our formula
