Cara and her brother take a numbered spinner from a board game and use it to determine

Oksi-84 [34.3K]

They are dependent events because if cara spins it and it lands on her she gets to play with the puppy, But if she misses it and her brother spins and it lands on him he gets to play with the puppy.

Short answer: the event is dependent because the outcome of the first spin effects the brother outcome

Graphs and lines. please help thx

Elodia [21]

Answer:

$y=\frac{4}{3}x+4$

Step-by-step explanation:

In order to identify the equation of line from the given graph, we need to find the slope and the y-intercept.

Slope of a line is the ratio of rise to run or change in $y$ over change in $x$ .

The y-intercept is a point on the line for which the $x$ value is 0. In other words, it is on the y-axis.

Here, from the graph,

y-intercept is at point (0,4). So, y-intercept is the $y$ value which is, $b= 4$ .

Also, slope is given as, $m=\frac{\Delta y}{\Delta x}=\frac{4}{3}$

Therefore, the equation of the line is:

$y=mx+b\\y=\frac{4}{3}x+4$
