Question

hhhheeeeeeeellllllllllp.....................

Find the equation of the line below. Arrange your answer in the form y = mx + b, where b is the constant. (Note: in this answer make sure your x has a coefficient)

(2,1)(-2,-1)

Answer 1

slope of line ( m ) = y2 - y1/x2 - x1 ,

tell me what u get

Answer 2

m=-2/-4

Answer 3

yep , that's 1/2 (simplified)

now to find b , use the equation y = mx + b

choose any point and plug in the values , now that u have m

Answer 4

1=1/2*2+b

Answer 5

b=0 and i need a fraction....

Answer 6

y-y1=m(x-x1)
y-1=1/2(x-2)
2y-2=x-2
2y=x
y=1/2x+0
This line passes through (0,0) so constant b=0

Answer 7

but my worksheet says it need to be a fraction...

Answer 8

check the points given.

Answer 9

how do u mean?????

Answer 10

I mean to say they may be different e.g.,(2,-1) or (-2,1) etc.

Answer 11

is the answer for this problem 0?????

Answer 12

Answer as given in the question is
y=1/2 x+0

Answer 13

ok, i get it,,, thank u soooo much....ps. what does coefficient mean..

Answer 14

In y=1/2 x+0
co efficient of x=1/2
coefficient of y=1
ax+by+c=0
coefficient of x=a
coefficient of y=b

Answer 15

thank u soo much.....
