Convert all the equations to slope-intercept form:
Lines A, B and C have the same slope as the line 2y-4x=3, so they are parallel and don't intersect it.
Line D has another slope, so it intersects the line 2y-4x=3.
The answer is D.

Answer:Answer: A negative correlation shows the relationship between two variables.
Step-by-step explanation: A) the correlation between the average SAT scores and percentage of high school seniors r = - 0.89 shows that the direction is negative and the relationship is strong.
B) SAT score = (-0.89 * proportion taking) + average score
Answer:
A
Step-by-step explanation:
to solve this problem, we can use the proportion method,
x /40 = 150/1
cross multiply
x (1) = (150)(4)
x = 600
