Question

given the equation y-4 =3/4(x+8) in point -slope form , identify the equation of the same line in standard form.

Answer 1

do you know the standard line equation?

Answer 2

no

Answer 3

y = mx +c, where m is your gradient, c is your intercept and x and y are x and y

Answer 4

so can you take your equation and rearrange it to make it y = something?

Answer 5

can u do that for me cuz i dont know how

Answer 6

I will try and help you understand so that you can do it,
So you start with this right:\[y -4 = \frac{ 3 }{ 4 }(8+x)\]
Can you expand the brackets on the right hand side?

Answer 7

sorry but kinda in a hurry can u give answer plz

Answer 8

okiii
from the point slope form...
y-4 =3/4(x+8)
we can directly get the slope...
here the slope is...
3/4

also.. we can get the co-ordinate of a point in the line
which is.. (-8 , 4)

now the slandered notation is
y = mx + c
hence we know the slope we can write it as..
y = 3/4x + c
now.. let's substitute the co-ordinates to the function..
4 = (3/4)(-8) +c
c = 10

so..the slandered form is
y = (3/4)x + 10

Answer 9

oh thx

Answer 10

u r welcome!!
