A(3,4) B(-3,2) C(-2,-4) D(6,-3)
slope = (y2-y1)/(x2-x1)
the first slope is 0 (horizontal line)
second slope is undefined (vertical line)
Answer: The graph is attached.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Given the first equation:

You can identify that:

By definition, the line intersects the x-axis when
. Then, subsituting this value into the equation and solving for "x", you get that the x-intercept is:

Now you can graph it.
Solve for "y" from the second equation:

You can identify that:
Notice that the slopes and the y-intercepts of the first line and the second line are equal; this means that they are exactly the same line and the System of equations has<u> Infinitely many solutions.</u>
See the graph attached.
Yes, it is an equivalent expression because even though you move two pieces of an equation it will still equal the same thing, unless there are parentheses involved.
Answer:
Correct option: first one
Step-by-step explanation:
The graph has 3 different parts:
Cost = 15 when the Gigabytes used is lesser than or equal 2,
Cost from 20 to 40 when the Gigabytes used is greater than 2 and lesser than or equal 6.
An increase of 4 gigabytes caused an increase of 20 in the cost, so the slope is 20/4 = 5, and the y-intercept is:
20 = 5*2 + b -> b = 10
Cost = 50 when the Gigabytes used is greater than 6.
So the correct option is the first one
