Question

can u check my work plz

Answer 1

these r to find the slope

a (2,2),(5,3)=(3,1)
and then i have b (1,-1),(4,-1)=(3,0)
and then c (2,-3),(2,9)=(),12)



are these right????

Answer 2

each is a separate problem all i need is to see if i got them right so for ex: i have (2,2),(5,3)=(3,1) i just need to see if (3,1)is right

Answer 3

do u understand or do u need more explanation

Answer 4

i need to know what the slope is just need u to check it

Answer 5

better now

Answer 6

@Mertsj

Answer 7

oh god ok so u know how to find slope right ... cuz if u dont then i dont know y u r thying to help me

Answer 8

*trying

Answer 9

sorry friend, my knowledge may be far lower than yours, cannot help, I ask Merstji already, he is very smart and knows many thing.

Answer 10

ok thanks for trying

Answer 11

the answers are incorrect and poorly written

for a \[m = \frac{3 - 2}{5 - 2} = \frac{1}{3}\]

the slope formula is

\[m = \frac{y_{2} - y_{1}}{x_{2} - x{1}}\]

so its difference in y divided by difference in x

for question (a) I used y2 = 3 and y1 = 2 x2 = 5 and x1 = 2

thats why I get the slope m = 1/3

does this make sense

Answer 12

a (2,2),(5,3)=(3,1) so slope = 1/3
and then i have b (1,-1),(4,-1)=(3,0) slope = 0/3=0
and then c (2,-3),(2,9)=(),12) slope = 12/0 = undefined

Answer 13

thank u @campbell_st and @Mertsj

Answer 14

you need to remember that slope is change in y OVER change in x.

Answer 15

yw

Answer 16

ok i will

Answer 17

And Hoa is a very smart guy...might be a little language challenged is all.

Answer 18

oh ok lol

Answer 19

@Mertsj I don't understand a word from those slope. thnaks for compliment

Answer 20

I know that you know how to find gradient
