Solution
- The transformation for reflection over the y-axis is given below:
- We have been given the coordinate of B to be (-5, -2) as shown below:
- Thus, applying the transformation formula given above, we have:
- Thus, the reflected point B' is
- This is shown below:
Answer:
y=4x
Step-by-step explanation:
The equation of a line is y=mx+b, where m is the slope and b is the y intercept.
The slope formula is Δy/Δx, so using the coordinates (1, 4) and (2, 8), the slope is which equals 4.
The y intercept is 0.
Therefore, the equation is y=4x.
