If you rotated the box 90º, the orrientation would not be the same, so it is not D or B.
After rotating 180º, the box will be in the 1st quadrant. If it moved along the x-axis, it wouldnt be there anymore, and the after-picture shows it in the first quadrant still, so the only answer it can be is C.
Answer:
i dont use it anymore but its IconixxJadaa i think
Step-by-step explanation:
Patients who visit a clinic for the first time are asked to answer 15 questions about their health history.
Survey
A researcher randomly chooses 20 patients who come to the clinic with the flu and gives them an experimental drug. A randomly chosen group of 20 patients who come in with the flu receive a placebo.
Experiment
A doctor at the clinic asks patients who come in with a headache how many hours of sleep they get on a typical night.
Observational Study
Step-by-step explanation:
the slope of the line is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
the trick in such a situation is to find good points on the chart that are crossed by the line. and by "good" I mean points with round integer coordinates.
I see 2 such points :
(-2, 3) and (0, -3)
x changes by +2 (from -2 to 0)
y changes by -6 (from 3 to -3)
the slope is -6/+2 = -6/2 = -3
