Question

Help guys ! :( Ill give a medal to the helper .
find the equation of the line indicated point with slope m

Answer 1

(5,0) , m = - 2/3

Answer 2

@UmarsBack

Answer 3

I think i need to use the Point Slope Formula

Answer 4

@annas mada'ame How did you do that?

Answer 5

oops forgot to take out value of b

Answer 6

oh and I'm sir xD

Answer 7

final equation will be y=-2/3x+10/3

Answer 8

sir help me please

Answer 9

I took that out from y = mx+b equation of a line

Answer 10

To start, you know what m is; it's just the slope, which you said was -2/3. So you can right away fill in the equation for a line somewhat to read:
y=-2/3x+b.

Answer 11

I cant use the equation thingy

Answer 12

To find b, think about what your (x,y) point means,
(5,0)
When x of the line is 5, y of the line must be 0.
Because you said the line passes through this point
right?
Now, look at our line's equation so far
b is what we want, the -2/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (5,0)

So, why not plug in for x the number 5 and for y the number 0?
This will allow us to solve for b for the particular line that passes through the point you gave!.

(5,0)
y=mx+b or 0=-2/3 × 5+b, or solving for b: b=0-(-2/3)(5)
=> b=10/3.

Answer 13

so the final eq you get is y=-2/3x+10/3

Answer 14

I hope that explains :)

Answer 15

@Dannica22

Answer 16

Look at this Given P(-7 , 1) and m = 3/4 (Use Point Slope Formula

y-y1=m(x-x1)
y-1=3/4(x+7)
4(y-1)=3(x+7)
4y-4=3x+21

so therefore :
3x-4y+25=0

Answer 17

@annas my bad ! hehehe not reading my notes. your point is I will use the Slope intercept Formula hehehehehe

Answer 18

:) sure and solution for second question is y=3/4x+25/4

Answer 19

wait Ill try it my self hehehehe

Answer 20

try one question by yourself cause as much as you practice your maths gets great :)

Answer 21

Can you make that equation into this equation x+y=0

Answer 22

On the second question I use Point slope Formula

Answer 23

sure
y=3/4x+25/4
-3/4x + y = 25/4
-3x + 4y = 25
-(3x - 4y)= 25
3x - 4y = -25
3x - 4y + 25 = 0

Answer 24

great :) you are pretty smart kido :)

Answer 25

Yeahhhhh it goes that thing !!!!!!!!!!!!!! Thank you !! But hahaha its kinda confusing a little but it help me a lot . Why is there something wrong with the Equation thingy in here?

Answer 26

I never tried equation thing xDD & no worries we are come here to learn & help :)

Answer 27

SO the first question with the answer of y=-2/3x+10/3 .. The equation goes like this 2/3x-y+10/3 = 0

Answer 28

y=-2/3x+10/3
2/3x + y = 10/3
2x + 3y = 10
2x + 3y - 10 = 0

Answer 29

Thank you (y)

Answer 30

anytime :)
