Question

Plz help.chose the point - slope form of the equation below that represents the line that passes through the point (6, -3) and has a slope of 1/2.

y-6 =1/2x+3)

y=1/2x-6

y+3=1/2 (x-6)

x-2y =12

Answer 1

first of all
there r only 2 choices which is given in point slope form... wt r they ?

Answer 2

um A an B

Answer 3

for the point slope form...they give you a point (x1, y1) and a slope m, and have you plug it into this formula:

y – y1 = m(x – x1)

can u guess it now.. ?

Answer 4

A an C i meant?

Answer 5

yep.. now according to the definition above.. can u guess the answer ?

Answer 6

A?

Answer 7

(x1 , y1 ) = ( 6 , -3)
which means
x1 = 6 and y1 = -3

now the format is
y – y1 = m(x – x1)

wt is the answer then ?

Answer 8

c

Answer 9

yep.. u r correct this time !!

Answer 10

ok thx

Answer 11

u r welcome!
