Y=mX+b WHERE X & Y ARE POINTS ON THE LINE, m=SLOPE & b=Y INTERCEPT.
FIRST WE SUBSTITUTE THE X & Y VALUES & THE SLOPE AND SOLVE FOR THE Y INTERCEPT(b).
2=2*3+b
2=6+b
b=2-6
b=-4 SO THE LINE EQUATION IS
Y=2X-4 OR WHEN GRAPHED WE GET
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+2x+-4%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = 2x -4).
