The slope of the line representing the linear graph is a rate of 3.2 meters per second.

<h3 /><h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and m is the y intercept.

Let y represent the distance in meters and x represent the time in seconds. Hence:

  • Using the points (20, 64) and (60, 192)

Slope = \frac{y_2-y_1}{x_2-x_1} =\frac{192-64}{60-20} =3.2

The slope of the line representing the linear graph is a rate of 3.2 meters per second.

Which of these graphs represents the graph of line y = -x + 1?
jok3333 [9.3K]

Answer:

See attached picture.

Step-by-step explanation:

To graph the equation, use the slope intercept form of the line to identify the slope and y-intercept.

y = -x + 1                          y = mx+b

m=-1 and b=1

This means start at 1 on the y-axis and plot a point. From this point (0,1), move down 1 unit and to the right 1 unit. Plot this point (0,1). Connect the two points.
