what then is the equation that pass through the given ordered pairs? @ParthKohli

parthkohli · Answer

First find the slope, and then the y-intercept.

parthkohli · Answer

You can find the slope with its formula.


$\Large \color{MidnightBlue}{\Rightarrow {1 - 4 \over 3 + 3} }$

$\Large \color{MidnightBlue}{\Rightarrow {-3 \over 6} = -{1 \over 2} }$

parthkohli · Answer

Then, the standard equation is y = mx + b
Slope is m, and it is -1/2.


$\Large \color{MidnightBlue}{\Rightarrow y = {-1 \over 2}x + b }$

Take any pair of points (x,y) given and substitute to find b.

Have you gotten the hint till now?

anonymous · Answer

m=1-(4)/3-(-3)
m=-3/3-(-3)
m=-3/3+3
m=-3/6
m=-1/2
