A keycode must contain 2 letters followed by 3 numbers. The letters may be
any letter of the alphabet The numbers should be any number from 0 to 9.
How many different keycode combinations are there?

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
