Question 1

x  varies directly as  p . If  x=14  when  p=2 , find  x  when  p  is 7 .
A)  x=1 
B)  x=14 
C)  x=49 
D)  x=343

Accepted Answer

Since x varies directly as p, the relationship between x and p can be represented as x = kp, where k is the constant of variation. Given x=14 when p=2, we can find k by substituting these values into the equation: 14 = k*2, which gives k=7. To find x when p=7, substitute p=7 into the equation x = kp: x = 7*7 = 49.

Find the slope of the line connecting the points  (-7,4)  and  (-7,9) .
A)  m=0 
B)  m=1.5 
C) undefined

Question 11

Find the slope of the line that passes through the points (-8, 2)and (-12, 2).
A)m = -4
B)undefined
C)m = 0
D)m = 1.4

Accepted Answer

The slope (m) of a line passing through two points (x1, y1) and (x2, y2) is given by m = (y2 - y1) / (x2 - x1). Here, m = (2 - 2) / (-12 + 8) = 0 / -4 = 0.
