Answer:
True
Step-by-step explanation:
I remembered learning this definition for a matrix:
A Matrix is an arrangement of numbers into rows and columns
so yes matrices consist of rows and columns
Answer: 
Step-by-step explanation:
The equation of the line slope-intercept form is:
Where m is the slope and b is the y-interecept.
The standard form is:
You know that must be parallel to 
, therefore both have the same slope. So you must solve for y:
Substitute the slope m=-1. Since the line passes through the origin b=0:
Then in standar form is:
If you would like to know how much flour does Bob have left, you can calculate this using the following steps:
5.5 cups of flour - 3.75 cups of flour = 5.5 - 3.75 = 1.75 cups of flour
Result: Bob has 1.75 cups of flour left.
If two lines have the same slope, then they are always parallel, unless they are the same line. Parallel lines means they never touch, but if you have the same line, they would be touching.
If two lines have the same slope and y-intercepts, then they are the same line, therefore not parallel because they touch each other.
