Answer:

The third option

Step-by-step explanation:

1. To determine whether a relation is a function given a graph, use the

following criterion:

  • if every vertical line you can draw goes though only 1 point, then the relation is a function
  • If you can draw a vertical line that goes though 2 or more points, y is  not a function of x.  
  • This is called the <u>vertical line test</u>.

2. As you can see, if you draw a vertical line at a specific place in the third graph, it will go through 2 or more points.

Therefore, the correct answer is the third option/graph.

If my phone bill is calculated using equation c= 50g +75 what is the value and interpretation of the slope of this equation? C=
olga nikolaevna [1]

Answer:

The value of the slope in this equation is 50

The interpretation is that the rate of change in the cost of the phone bill per unit change in gigabytes of data used each month is 50

Step-by-step explanation:

To answer this question, we need to compare the given equation with the equation of a straight line graph.

The equation we have is;

c = 50g + 75

comparing this with the equation of a straight line, we have

y = mx + c

where m represents the slope and c is the y-intercept

So comparing both, the slope of the equation is 50.

The slope is always the co-efficient of the value on the x-axis

So what does this mean?

The slope also called the gradient represents the rate of change of the y-term divided by the rate of change of the x-term. In simpler terms, when we talk of the slope, we mean the rate of change of the y term per the unit change of the x-term.

So what we mean in this case is the rate of change in cost of the phone bill per unit change in gigabytes of data used each month is 50
