Part a: which point represents the origin? (2 points)

part b: starting from the origin, explain how to plot the following three points accurately:

(−1, 1)
(1, −1.5)
(2, fraction 1 over 4)

A) (0,0) is the origin

B) (1, -1)... Go right on the X-Axis to 1. Then go down on the Y-Axis to -1. That will be your first point.

(-1, 1.25) Go left on the X-Axis to -1. Then go up on the Y-Axis to 1.25. That will be your second point.

Finally, (-2, 3/4) Go left on the X-Axis to -2. Then go up to 3/4 on the Y-Axis. That will be your final point.

Step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
