Question

Choose the equation of the line passing through the point (-1, 3) and perpendicular to y = -1/3 x + 7.

y = 3x - 12
y = 3x + 6
y = 3x - 6
y = 3x

Answer 4

well, we know that 3x is going to have to be a part of it right?

Answer 5

@sleepyjess

Answer 6

choose the option that when x=-1, y=3

Answer 7

yes

Answer 8

D ?

Answer 9

lets test that option ...

3 = 3(-1)

is this a true statement?

Answer 10

one idea, if trial and error is not your strong point is to solve the setup

3 = 3(-1) + b to find the correct ending term

Answer 11

y = 3x + 6

Answer 12

but its not a true statement

Answer 13

b is correct @IndianBoyNiko

Answer 14

Thank you

Answer 15

The equation of a line is shown below:

y = - x - 7

What is the equation of a line which is parallel to this line and passes through (1, 79)?

y = -x + 80
y = x - 80
y = 7x - 80
y = -7x + 80

Answer 17

@sleepyjess

Answer 18

It must have the same slope so you can already take out 2 options.

Answer 19

which ones ?

Answer 20

Actually you can take 3 out

Answer 21

which ones ?

Answer 22

The first term MUST be -x

Answer 23

so A ?

Answer 24

y = -x + 80

Answer 25

Yes and to confirm that substitute 1 for x

Answer 27

Thank you

Answer 28

@princeharryyy Do not give out direct answers please.

Answer 29

The first five terms of a sequence are shown below.

5, 9, 13, 17, 21

If the nth term of this sequence is represented by f(n), which of the following functions best represents this sequence?

f(n) = 5n - 1; n ≥ 1
f(n) = 5n + 1; n ≥ 1
f(n) = 4n - 1; n ≥ 1
f(n) = 4n + 1; n ≥ 1

Answer 30

This one was the hardest but I got C

Answer 31

but idk if it's right

Answer 32

One question per post please

Answer 33

f(n) = 4n + 1; n ≥ 1
simply plugin and check verifies all

Answer 34

Substitute in a number.
f(1)= 5(1) - 1; n ≥ 1
f(n) = 5(1) + 1; n ≥ 1
f(n) = 4(1) - 1; n ≥ 1
f(n) = 4(1) + 1; n ≥ 1
