Assuming this is written correctly, with no x in the equation, we just solve for y:
y = -3 - 1/3 = -10/3 = 0 x - 10/3
That's slope-intercept form.
Answer: Slope 0, y-intercept -10/3
I think it’s 3 times because 2*3=6 and 4*3=12 and 6*3=18
If one shirt equals to $21.46, and you need to purchase 4 shirts to get the free pair of jeans, you multiply 4 by 21.46 and get 85.84. But if there is 42 customers taking advantage of the special, then you need to multiply 85.84 by 42, and you get 3,605.28.
