What is “y greater than or equal to 1/2x graphed using the formula y=Mx+b”??
dimulka [17.4K]

Answer: The graph is attached.

Step-by-step explanation:

The Slope-Intercept form of the equation of the line is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

When the line passes through the origin:

b=0

Then:

y=mx

The exercise gives you the following Inequality:

y\geq \frac{1}{2}x

You can identify that line is:

y=\frac{1}{2}x

As you can notice, the line passes through the origin and its slope is:

m=\frac{1}{2}

The symbol \geq indicates that the line is solid and the shaded region must be over the line.

Knowing the above, you can graph the Inequality (Observe the graph attached).

To help you with this topic, I would suggest you revise probability trees.

P(train arriving) = 0.8
P(train arriving on time) = 0.84
P(train arriving late) = 0.86

0.8 x 0.86 = 0.688
