Is this a zero? or a negative? or a positive or an undefined?

Do you mean the slope? if so, the slope is undefined. however, the equation for the line would be written as y=3 since all the y values on that line are equal to three. hope this helped!

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
