Annie is creating a stencil for her artwork using a coordinate plane. The beginning of the left edge of the stencil falls at (2, −1). She wants to align an important detail on the left edge of her stencil at (4, 1). She knows this is 1:4 of the way to where she wants the end of the stencil. Where is the end of the stencil located?

Randolph is creating rectangle WXYZ so that WX has an equation of y = 1 over 4x + 4. Segment XY must pass through the point (−2, 6). Which of the following is the equation for XY?

y − 6 = 1 over 4(x − (−2))
y − (−2) = 1 over 4(x − 6)
y − 6 = −4(x − (−2))
y − (−2) = −4(x − 6)

Carla and Jonah are working together to determine if quadrilateral CDEF with coordinates C(2, 3), D(1, 2), E(4, 1), and F(5, 3) has perpendicular sides.

Carla sets up the following equations:
slope of segment CD equals 2 minus 3 all over 1 minus 2
slope of segment DE equals 1 minus 2 all over 4 minus 1

Jonah sets up the following equations:
slope of segment CD equals 2 minus 3 all over 1 minus 2
slope of segment EF equals 3 minus 1 all over 5 minus 4

Who is on track to get the correct answer, and why?

Carla is on the right track because she is finding the slopes of consecutive sides to check for perpendicular sides.
Carla is on the right track because she is finding the slopes of the opposite sides to check for perpendicular sides.
Jonah is on the right track because he is finding the slopes of the opposite sides to check for perpendicular sides.
Jonah is on the right track because he is finding the slopes of consecutive sides to check for perpendicular sides.
