The answer is y=1/2x + 7.
The plot is (-2,2), so what it actually is, is (x,y) so you always have the same slope when lines are parallel. So you just need to solve for the y-intercept. so you substitute -2 in for x and you get the y-intercept! Hope this helps!
Answer: Choice C)
(1/30)*(1/29)
Explanation:
Jack has a 1/30 chance of being picked since he is 1 person out of 30 total. After his name is picked, and not put back, there are 30-1 = 29 names left. The chances Jill is picked is 1/29. The two fractions are multiplied to get the overall probability both are picked.
If you divide 90 to 18, you would get 5. therefore, 5cm is the answer.
