Question 270397: How can I write the general form of an equation of the line that passes through two points? (1,4) (5,6). Thank you! Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! (1,4) (5,6)
Y=mX+b m=slope & b= the Y intercept.
m=(Y2-Y1)/(X2-X1)
m=(6-4)/(5-1)=2/4=1/2 ans. for the slope.
4=1/2*1+b
4=1/2+b
b=4-1/2
b=3 1/2 or 7/2 is the Y intercept.
Y=X/2+7/2 line equation. (graph 300x200 pixels, x from -8 to 5, y from -10 to 10, x/2 +7/2).
