Question

Which equation represents the graph of the linear function?



A.
y = −3x + 1

B.
y = −3x − 1

C.
y = 3x + 1

D.
y = 3x − 1

Answer 1

will fan and medal

Answer 2

i need a tutor if anyone has kik to tutor me on

Answer 3

Find the slope from the graph
(rise/run)
this will equal the coefficient of x in the equation

then the number after the 3x is the intersect on the y-axis

Answer 4

ok is that all

Answer 5

D

Answer 6

Can you observe a line and tell if the slope is negative or positive ??

Answer 7

negative

Answer 8

Here is a hint if the line rises to the right it is positive.
if it falls or goes downward to the right it is negative.
Here as in the previous problem you can get rid of half of the answers just by looking at the line.

Answer 9

its positive
so its y = −3x + 1 (A)

Answer 10

y = −3x + 1 i meant

Answer 11

If it is positive that means the coefficient of the x term has to be positive when the line equation is in the form y = 3x - 1.

Answer 12

No the line is like / so its positive
its 3x

Answer 13

its A right

Answer 14

@radar

Answer 15

To determine which one, now observe the graph, find y when x is zero.

Answer 16

y=4

Answer 17

or y=-4

Answer 18

Or you looking at the line you furnished with the link ??

Answer 19

What is the value of y when x = 0 for this line?

Answer 20

what???

Answer 21

Look at your problem, the graph provided by your link ( 1.jpg) What is the value of y when x=0?

Answer 22

its B i think

Answer 23

No it is going to be a number value, very simple to obtain, look at the line and see what its y value is when x = 0.

Answer 24

-3

Answer 25

right

Answer 26

On the graph I see it is -1.

Answer 27

ya i see it now

Answer 28

With that info you can select the correct answer. Good luck with your studies. You really don't need a tutor, you just need to apply yourself.

Answer 29

ok thx

Answer 30

so its D
