What is a Rectangular Coordinate System? * a. It is used for naming points in a plane.
b. Is a plane used for graphing linear functions.
c. It is used to determine the location of a point by using a single number.
d. It is a two-dimensional plane which is divided by the axes into four regions called quadrants.

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

you can download it here

they can either have 0,1, or infinite solutions

step-by-step explanation:

your answer is b.

step-by-step explanation:

the 2 points are: (3,1) and (6,6)

first, let's find the slope:

(6-1)/(6-3) = 5/3

then let's plug this into the point-slope formula:

y - 1 = 5/3(x - 3)

this is your answer! the below is just the simplified form.

y - 1 = 5/3x - 5

y = 5/3x - 4
