Write the equation of the line that passes through the
Butoxors [25]

Answer: y = 2x also written as y = 2x + 0

Step-by-step explanation:

When dealing with parallel lines their slopes are ALWAYS the same so the equation would have the slope of 2, but to find the y intercept you have to plug the coordinate given into the point-slope formula (y - y1) = m(x - x1) where m is the slope, y1 is the y output of the coordinate and x1 is the x input of the coordinate.

1. Plug cordinate into point slope form equation:

(y - 0) = 2(x - 0)

2. Distribute the 2 to x and 0

y - 0 = 2x - 0

The two zeros cancel out because they are 0s to begin with so your final answer for your y - intercept is 0

hope this helps :)

The triangles shown are congruent by the SSS congruence theorem.
denis23 [38]
1. Let's check the problem backwards. So let's map A"B"C" to ABC

2. We first need to reflect  A"B"C" to A"B"C' with A"B"" as the axis of rotation.

3. Then we shift a few units up (translation) A"B"C' to A'B'C

4. Finally we rotate A'B'C around C to map the triangle onto ABC

going backwards we get the answer: b
