The graph of a system of equations with the same slope and the same y-intercepts will have no solutions.

Rasek [7]

If 2 equations have the same y-intercept, they are overlapping, which means they have infinite solutions. So there is no way that 2 equations with the same y-intercept will have no solution. Thus your answer is: C)Never.

Answer:

$\frac{1}{45}$

Step-by-step explanation:

There are

2 yellow

3 magenta

5 blue

marbles in the bag.

So total of 2 + 3 + 5 = 10 marbles

We have to multiply the probability of yellow on first pick by the probability of yellow on second pick (WITHOUT REPLACEMENT).

We denote P(Y1) as probability of yellow on first draw &

P(Y2) as probability of yellow on second draw

Thus,

P(Y1) = 2/10 = 1/5 [since 2 yellow and 10 total marbles]

Now,

P(Y2) = 1/9 [since now 1 yellow is taken out and NOT replaced, so we have 1 yellow remaining and total 9 marbles]

Now, we multiply:

P(Y1) * P(Y2) = 1/5 * 1/9 = 1/45

The probability is $\frac{1}{45}$

M= 0 passes through the point (-1,3)

Len [333]

Answer:

y = 3

Step-by-step explanation:

I will assume you want to put this in slope intercept form.

We need to solve for b in y = mx + b since we are given a point and the slope.

y = 0x + b

y = b

3 = b

y = 3

Note that since the slope is 0, there will be nothing to represent m.

Best of Luck!
