A banker’s compensation consists of a weekly salary as well as a commission for each account opened. The banker earns commission at a rate of $10/account. In one particular week, the banker opened 15 accounts and brought home a total pay of $830. Which of the following equations describes the pay for the banker in terms of accounts opened?
A.
y = 10x + 15
B.
y = 10x + 68
C.
y = 15x + 680
D.
y= 15x + 830

Answer 1

I believe it's D. y= 15(amount of accounts opened) plus the base pay of 830.

Answer 2

Scratch that. It's C. His TOTAL salary is 830, but his base pay is 680.

Answer 3

What is the equation of the line that passes through the points (4/5, 1/5) and (1/2, 3/2?
A.
y = –x – 1

B.
y = –x + 1

C. y=-13/3 x + 11/3

D. y= 7/3 x +1/3

Answer 4

@Aydia thankyou!

Answer 5

Here's for the second question.

y=-13/3x+11/3

Answer 6

What is the slope of a line that is perpendicular to 6x + 3y = –9?
A.2
B.1/2
C.-2
D.-1/2

Answer 7

The next one is B.

Answer 8

Are you sure it is B? Whats wrong with D.

Answer 9

I'm fairly sure. D is negative when it needs to be positive.

Answer 10

I think A is the answer.

Answer 11

What is the equation of the line that has a slope of 4/5 and a y-intercept of –1?
A.y=4/5x-1
B.y=4/5x+1
C. y=-x+4/5
D.y=-x-4/5

Answer 12

thankyou both you don't know how much of a life saver you are!! seriously

Answer 13

I don't like numbers 😒

Answer 14

A perpendicular line would have the negative reciprocal of the slope of the line which it is perpendicular to. Isn't that slope a - 1/2, wouldn't the negative reciprocal be a +2?

Answer 15

Never mind I am wrong

Answer 16

What is the equation of the line that passes through (4, 2) and is parallel to 3x – 2y = –6?
A. y=-3/2 x+8
B.y=3/2x-4
C.y=1/2x
D.y=2/3x-4

Answer 17

the slope of the given line 6x + 3y = -9 is -2
the negative reciprocal is as you say a 1/2

Answer 18

thankyou!!

Answer 19

The equation of a line is y=1/4x-2. What is the equation of the line that is parallel to the first line and passes through (4, –2)?
A.y=-4x+14
B.y=-1/4x-1
C.y=-4x+3
D.y=1/4x-3

Answer 20

Two lines are parallel. The equation of the first line is y = –3x + 5. Which of the following cannot be the equation of the second line?




A.

y = –3x + 2


B.

x – 3y = –3


C.

3x + y = –6


D.

6x + 2y = 2
