You can put this solution on YOUR website! What is the equation of the line?
(3,4)(9,9)
.
First, determine the slope given the two points:
m = (y2-y1)/(x2-x1)
m = (9-4)/(9-3)
m = 5/6
.
Now, you can plug one of the two points say, (3,4) and the slope (5/6) into
y-y1 = m(x-x1)
y-4 = (5/6)(x-3)
y-4 = (5/6)x - 5/2
y = (5/6)x - 5/2 + 4
y = (5/6)x - 5/2 + 8/2
y = (5/6)x + 3/2 (this is the equation of the line)
