Graph your data scatterplot The xaxis should represent the t

Graph your data (scatterplot). The x-axis should represent the trial number and the y-axis should represent the number of MSM/cancer cells. What is the value of the y-intercept in the graph? What does the y-intercept represent in the context of this problem?

Solution

According to the graph, since the graph is a straight line

Let the equation of Line

y = mx + C

at value of x=1.5, the value of y=10

at the value of x=3, the valye of y=20

10 = 1.5m + C

20 = 3m + C

Hence the value of m = 20/3 and C=0

Therefore, the equation of line will be equal to

y = 20/3x

Hence the y-intercept will be when y=0, which means x=0

The y-intercept denotes the number of M&M cancer cells since the start there will be no M&M cancer cells
