Y=mX+b IS THE LINE EQUATION. THUS REPLACING (m) BY 3 & (Y) BY 17 & (X) BY 4 WE SOLVE FOR THE Y INTERCEPT(b)
17=3*4+b
b=17-12
b=5 THE Y INTERCEPT. THUS THIS LINE EQUATION IS ---
Y=3X+5
+graph%28+400%2C+400%2C+-20%2C+20%2C+-20%2C+20%2C+Y+=+3X+%2B5%29+ (graph 400x400 pixels, x from -20 to 20, y from -20 to 20, Y = 3X +5).
