Gabe is mapping out important family events. He uses negative numbers to represent a time before he was born and positive numbers to represent the time after he was born. For example, Gabe's mom was given a special coin in a year −20minus, 20, and Gabe's sister was born in year 5.

What does year 0 represent?

true? is that what you're asking or do you mean something else?

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
