Writing Equations from a Table In your equations, do not enter 1x or -1x, just x or -x (for example: y = 1x + 3 should just be y = x + 3)
Also, do not enter a plus negative, just subtract. (for example y = 2x + -3 should just be y = 2x - 3)
Do not enter + 0. (for example y = -3x + 0 should just be y = -3x)
Finally, put the x term first. y = 25 - 2x should be entered as y = -2x+25 (even though both are correct) x y 0 5 y = 1 7 2 9 11 3 x y 0 1 y = 1 5 2 9 13 3 x y 0 25 y = 1 22 2 19 16 3 x y 0 -1 y = 1 0 2 1 2 3 x y -2 11 y = -1 9 0 7 5 1 x y -1 -8 y = 0 -5 1 -2 1 2 x y 120 0 y = 135 1 150 2 165 3 x y -21 -3 y = -14 -2 -1 -7 0 0 x y -1 3 y = -6 0 -15 1 -24 2 x y 1 5 y = 2 7 3 9 11 4 x y 2 14 y = 3 11 4 8 5 5 x y -20 -4 y = -12 -3 -2 -4 -1 4 x y 4 13 y = 5 14 6 15 16 7 x y -2 0 y = 1.2 -1 2.4 0 3.6 1 x y 0 -1 y = -9 4 -11 5 -15 7 |
