PLEASE ANSWER

Which equation represents the line of best fit?

A. y= 10x + 45
B. y = x + 45
C. y = −10x+ 45
D. y = 45x + 10

The equation that gives the line is A.

Step-by-step explanation:

Step 1:

First, we need to plot some points on the line on the graph. Some of the points are (1, 55), (3, 65), and (3, 75).

We need to find which of the given equations relating the x values to the values of y in the determined coordinates.

y is the dependent value whereas x is independent i.e. the y value changes according to the x value.

Step 2:

Now we substitute the values in the given equation to see which corresponds correctly.

For , when x = 2,

For , when x = 2,

For , when x = 2,

For , when x = 2,

Only the first equation gets a value of y, that corresponds to a coordinate on the line of the graph, so A.  represents the line of best fit.

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
