Slope intercept form: y = mx + b

Where m = slope and b = y-intercept.

By looking at the graph, we can see that the line cuts at 1/2 on the y-axis, therefore eliminating option D.

So now we have: y = mx + 1/2

Next, we'll find the slope. \frac{y_2-y_1}{x_2-x_1}

Plug the coordinates into the formula.

\frac{3-(-2)}{4-(-4)}= \frac{5}{8}

So our slope is 5/8 and the y-intercept is 1/2.

Option A is the answer.

Brian spins a fair spinner numbered 1 - 5 and flips a fair coin.
Greeley [361]

Answer:  0.1

Step-by-step explanation:

If we spin a fair spinner numbered 1 - 5 and flips a fair coin.

Then, the possible outcomes will be :-

(1,T),(2,T), (3,T), (4,T), (5,T)\\\\(1,H),(2,H), (3,H), (4,H), (5,H)

i.e. total 10 possible outcomes.

The favorable outcomes = a 2 and a head  i.e. only 1 .

Now, the probability of obtaining a 2 and a head will be :_

\dfrac{\text{Number of favorable outcome}}{\text{Total outcomes}}\\\\=\dfrac{1}{10}=0.1

Hence, the  probability of obtaining a 2 and a head = 0.1

Identify the slope and the y-intercept of<br> the line with the given equation:<br> 2x+6y=12
Elza [17]

Answer:

The slope is -1/3 and the y-intercept is (0, 2).

Step-by-step explanation:

2x+6y=12

6y=12-2x

6y=-2x+12

y=-2/6x+12/6

y=-1/3x+2

y=mx+b where m=slope and b=y-intercept
