Help Me! ASAP! I will mark the brainliest! Audra plays the piano and wanta to play more songs. She decides to learn the same number of new songs every month. She makes a graph to show the number of songs she learns. Which Stateement is true? A. The slope is 1/2.
B. The slope is 5.
C. The point (20, 45) is on the line.
D. The y-intercept represents the number of months Audra has been playing piano.

C. The point (20, 45) is on the line.

Step-by-step explanation:

The number of songs learned by Audra vs the number of months is plotted in the graph provided.

Some points are recognized from the graph: (0,5) (1,7) (2,9) among others. With two of these points, we construct the linear model of the graph.

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

Using (0,5) and (1,7):

y - 5 = 2x

y = 2x + 5

The slope of the line is 2. So, A. and B are discarded.

The y-intercept represents the number of songs Audra played initially at time = 0.

The point (20,45) is on the line as we'll prove below:

y = 2(20) + 5 = 40 + 5 = 45

When x=20, y=45

Thus, the correct choice is:

C. The point (20, 45) is on the line.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
