9x - y = -2
Part A. To find the solutions that satisfy the equation, find the corresponding values of y for each given value of x.

Part B. Let x = -3, 9(-3) - y = -2
y = -27 + 2 = -25
Let x = 0, 9(0) - y = -2
y = 2
Let x = 3, 9(3) - y = -2
y = 27 + 2 = 29
Therefore, three different solutions are (-3, -25), (0, 2), (3, 29)

Part C. Pairing the equation with 18x - 2y = 5 will result in a system of equations that is inconsistent.

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.
