Coordinate Geometry

Francisco draws triangle ABC on a coordinate grid. The slope of line segment AB is 3/4. Francisco then transforms triangle ABC using a single transformation to create A'B'C'. He claims the slope of A'B'will still be 3/4. Which of the transformation described support Francisco's claim, check ALL that apply:

• Rotation of 180 degrees around the origin

• Reflect across the line y=-2

• Translate up 1.25 units

• Reflection across the x-axis

• Dilate from the Origin with a scale factor of 3
