The graph which can show trends over time is the
a.
circle graph
c.
line graph
b.
pie chart
d.
bar graph

The correct option is line graph

Step-by-step explanation:

Given some graph names

we have to choose the graph which show trends over the time.

As we know the pie chart and bar graph works on data and gives the constant value implies cannot show trends over time.

The circle graph also not work with increment of time as it goes around the same point with same distance from centre. Hence, this graph also not  show trends over time.

The line graph also called line chart, it is a type of chart used to visualize the value of something over time.

For example, a finance department may plot change in the amount of cash the company has on hand over time. The line graph consists of a horizontal x-axis and a vertical y-axis.

Hence, the correct option is line graph

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
