I'm guessing you mean what a linear function is, answer provided below...

What is a linear function?:

linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.

How to determine a linear function:

1. Identify the y-intercept from the graph.

2. Choose two points to determine the slope.

3. Substitute the y-intercept and slope into slope-intercept form of a line.

Here is a graph with a linear function:

Write the standard equation of the circle with the given center and passes through the given point. Center (7,-2); Point= (1,-6)

vodomira [7]

Answer:

(x - 7)² + (y + 2)² = (2√13)²

Step-by-step explanation:

We already know that the center is at (7, -2), but must find the radius. The radius is the distance between the points (7, -2) and (1, -6):

r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.

Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²
