Answer:
y-2=2/3(x+1) OR y=2/3x+8/3
Step-by-step explanation:
y=2/3x-2 (2/3 represents your slope)
plug into this equation y-y1=m(x-x1) (m represents your slope, y1 and x1 are you points)
so y-2=2/3(x+1) OR y=2/3x+8/3 (move the -2 over, distribute the 2/3 to (x+1) and then add 2/3 to the 2 you moved over)
Answer: She can randomly survey 50 seventh-graders in the school.
Step-by-step explanation: To get the best result without wasting to much time means she cannot afford to survey every student. To receive the best results it should be unbiased so random is the way to go. Randomly surveying 50 girls in her school does not guarantee that those girls are all seventh graders so the best answer is She can randomly survey 50 seventh-graders in the school.
