Question 154564
Y=mX+B (red line)
Y=3X+4 THIS LINE HAS A SLOPE=3 & A Y INTERCEPT=4.
{{{ graph( 300, 200, -6, 5, -10, 10, 3x +4, y = -6) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions 3x +4 and y = -6).
----------------------------------------
slope=(-6+6)/4-2)=0/2 represents a horizontal line through -6 (green line).
