When point b (5, -1) is rotated 180º about the origin, its coordinate becomes (-5, 1). true false

When a point (x,y) rotated 180⁰ about origin, the new point will be (-x, -y).

So,

if we have (5, -1), it should become (-5, 1).

So,

answer is true.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
