Graph the line of the equation x4+y=−2 using its slope and y-intercept
k0ka [10]

Answer:

y-intercept = c = -2

slope = y = - 4

Step-by-step explanation:

The correct equation is:

4x + y =  -2

We need to graph the line using its slope and y-intercept. The slope intercept form of the equation is:

y = mx + c

Here, m is the slope and c is the y-intercept. Transforming the given equation to this form gives us:

y = - 4x - 2

This means, the slope is:

m = - 4

and y-intercept is:

c = - 2

y-intercept in ordered pair is written as (0, c). So for the given case the y intercept will be (0, -2). This gives us first point on the graph.

The slope tells us that by how many units will the y variable will change for one unit change in x-axis.

So slope, m = - 4, tells us that the y-variable will change by negative 4 units for 1 unit change in x variable.

Based on this change, we can get another point from (0, -2) which will be (0+1, -2 - 4) = (1, - 6)

This gives us the second point on the graph. Plot these two points and join them using a straight line. This straight line will be the graph of equation y = 4x - 2 or 4x + y = -2

The graph is attached below.

Of students in the AP curriculum at a prep school, 40% take one AP exam, 45% take two AP exams, and the remaining 15% take 3 AP
aliya0001 [1]

It should be noted that the probability that a student will earn at least one 5 will be 0.3152.

<h3>How to calculate the probability</h3>

Test P(x). P(at least one 5)

1. 0.4. 0.2

2. 0.45. 0.36

3. 0.15. 0.488

Therefore, the probability that a student in the AP curriculum will earn at least one 5 will be:

= (0.4 × 0.2) + (0.45 × 0.36) + (0.15 × 0.488)

= 0.3152

In conclusion, the correct option is 0.3152.
