Question

Andrea collected data for a school project, but accidentally spilled her coffee on her page. She knows that the values represented a linear function. For this function, what is the value of y when x = 4?

Answer 1

Answer:

The answer is below

Step-by-step explanation:

The question is not complete.

The equation of a linear function is given by the formula: y = mx + b, where m is the slope, y is a dependent variable and x is an independent variable. The linear function passing through the point $(x_1,y_1)\ and\ (x_2,y_2)$ is given by:

Let us assume the data collected has the point (0, 0) and (60, 30). The equation of the linear function is:

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{30-0}{60-0} (x-0)\\\\y=\frac{1}{2}x$

To find value of y when x = 4 ,we substitute x = 4.

$y=\frac{1}{2}(4)\\\\y=2$
