Answer 3

oh gosh im not good at math I wish I can help but I don't know what the answer would be

Answer 4

The graph of a first degree polynomial is always a straight line. The graph of a second degree polynomial is a curve known as a parabola. A polynomial of the third degree has the form shown on the right. Skill in coördinate geometry consists in recognizing this relationship between equations and their graphs. Hence the student should know that the graph of any first degree polynomial y =ax + b is a straight line, and, conversely, any straight line has for its equation, y =y + g

Answer 5

im sorry i dont understand some of that.

Answer 6

@jewelry02 just find two points where the line intersects the axes

Answer 7

-3 and 1

Answer 8

but thats not an answer

Answer 9

Thats hint

Answer 10

@priyar

Answer 11

Not givin answer :|

Answer 12

ya that was just a start...

Answer 13

oh

Answer 14

u mean (-3,0 ) and (0,1) right?

Answer 15

its not 1?

Answer 16

y-intercept is the length from origin to the point where the line meets the y-axis

Answer 17

so what will the y-intercept be?

Answer 18

its D

Answer 19

right?

Answer 20

how?

Answer 21

in option D y takes value zero so its point of x-intercept..

Answer 22

well its definently not b or c

Answer 23

what makes u think so?

Answer 24

guys can you just help her poor thing she dosent know the answer

Answer 25

because they are positive

Answer 26

so what..here the graph cuts y axis at 1 so the point is (0,1)...that rounds it off two b or c

Answer 27

to find the answer we must find the slope..

Answer 28

and we can do that by?

Answer 29

we have 2 points that i wrote above..use that in the below formula

Answer 30

\[slope=y1-y2/x1-x2\]

Answer 31

where (x1,y1) and (x2,y2) represent two points

Answer 32

just plug in the values

Answer 33

I'm sorry but i don't know what points and where i put them. i don't know what the 1's are for. i just nevermind can you let me know where they go at least?

Answer 34

ok let me do this one for you as an example:
\[0-1/-3-0\]

Answer 35

i got this coz these were our points:
(-3,0 ) and (0,1)

Answer 36

.333333....

Answer 37

or in a simpler way:1/3!!

Answer 38

so which option is it?

Answer 39

i said D you never said whether it was right or wrong

Answer 40

its wrong..

Answer 41

we got slope:1/3 and the y intercept point:(0,1) then how can it be D??

Answer 42

then is it B

Answer 43

C

Answer 44

good!
