Question

What is the equation of the line that passes through the points (1,2/3) and (-1,-1) ?
A.y=-6x+5

B.y=5/6x-1/6

C.y=2/3x+1/5

D.y=6/5x+1/5

Answer 1

can you find the slope of line first ?

Answer 2

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 3

alright thank you :)

Answer 4

after you get the slope,m
you use
\(y-y_1=m(x-x_1)\)
where x1,y1 is any one of the 2 points...

Answer 5

alright i understand it a little better now :)
