You can put this solution on YOUR website! Complete the equations of the system in slope-intercept form. Use a decimal for the slope if necessary.
Line 1
x y
0 3
----
Is it the point (0,3) ?
At least 2 points are needed.
=================
Line 2
x y
–1 1
–2 –1
----------------
If it's (-1,1) and (-2,-1):
Slope m = diffy/diffx = -2/-1
m = 2
----
Use y-y1 = m*(x-x1) where (x1,y1) is either point
Using (-1,1):
y-1 = 2(x+1)
y = 2x+3
-------------------------
