Identify two coordinates on the graph
------------------------------------------------------------------------------------------
( 0, -1) and (3, 0)

------------------------------------------------------------------------------------------
Apply the formula for Slope
-------------------------------------------------------------------------------------------

$\boxed{ Slope = \frac{Y_2-Y_1}{X_2 - X1} }$

$\boxed {Slope = \frac{0-(-1)}{3-0}}$

$\boxed { Slope = \frac{1}{3} }$

I need a little help! Can someone check my work? It's a written response with linear systems.

andreyandreev [35.5K]

Answer:

I'd say you need to be more specific.

Step-by-step explanation:

"Different" doesn't tell you much.

Consider the equations ...

y = 2x + 1
4x - 2y = -2

These equations are "different", but they are dependent.

_____

I'd mentally (or actually) put the equations in the same form and compare the coefficients of x and y. If they have different ratios, the system is independent and consistent.

If they have the same ratio, the system will not have a single solution. Whether there is no solution or an infinite number of solutions depends on the constant, which I would examine next.

The system above can be put in the form

2x -y = -1
4x -2y = -2

In both cases, the ratio of the x coefficient to the y coefficient is 2/-1 = 4/-2 = -2. This means the lines are at least parallel, if not identical. The numbers in the second equation are all 2 times the numbers in the first equation, so the equations are dependent, and there are an infinite number of solutions. (Both describe the same line.)

If the second equation were 4x -2y = 1, then the two equations would be describing parallel lines, so they would be called inconsistent.

Car A began a journey from a point at 9 am, traveling at 30 mph. At 10 am car B started traveling from the same point at 40 mph

mafiozo [28]

At 10 am, Car A is at 30 miles.

Then at 11 am, Car A is at 60 miles and Car B is at 40 miles

At 12 am, Car A is at 90 miles and Car B is at 80 miles

At 1 pm, Car A and B are tied for 120 miles

The very second after Car B passes Car A

Answer: 1:01 pm Car B Passes Car A
