Answer: The graph is shown in the attached image below</h3>
-2x means -2*x or "-2 times x" where x is a placeholder for any number you want.
To graph y = -2x, you just need two points. Each point is of the form (x,y)
Let's plug in zero as it is often the easiest to work with.
If x = 0, then -2*x = -2*0 = 0. Notice how I replaced x with 0 and simplified.
Therefore, if x = 0, then y = 0. We have (x,y) = (0,0) as one point on this line. I have marked it as point A in the graph.
Point B is (1, -2) and it is found by plugging x = 1 into the equation to get...
y = -2x
y = -2*1
y = -2
You could find other points, but two points is enough to draw a straight line through them. The slope of this line is -2 = -2/1. The y intercept is 0.
Answer:
0.0224 or 2.24%
Step-by-step explanation:
The probability that an intern uses drugs, given that the test is negative, is determined by the probability of false negative divided by the probability of a negative (true or false).
A false negative occurs when an intern who uses drugs (10%) takes the test and gets a negative. Since the test gets it right 80% of the time, the probability of this happening is:
A true negative occurs when an intern who does not use drugs (90%) takes the test and gets a negative. Since the test gets it wrong 3% of the time, the probability of this happening is:
Therefore, the probability that an intern uses drugs, given that the test is negative is:
The probability is 0.0224 or 2.24%.
slope intercept form - (y = mx + b)
slope (m) is (3/2) So, y = 3/2x + b
To find b you plug in the x and y value (2,7)
7 = 3/2 × 2 + b
Isolate x on one side by finding the value of 3/2 × 2 which is 3.
Subtract 3 from both sides which leaves you with 4 = b, so the value of b is 4
Now the slope intercept form is (y = 3/2x + 4)
