Question

How do we know that the point (-0.8, -0.6) is a solution to the system of equations when the corresponding y-value is -0.6?

Answer 1

To determine whether a point is a solution to a system of equations, substitute the x and y values into the equations and solve for the variables.

Step-by-step explanation:

To determine whether the point (-0.8, -0.6) is a solution to the system of equations, we substitute the x-value (-0.8) and the corresponding y-value (-0.6) into the equations and see if they satisfy the equations. Let's assume the system of equations is represented as:

Equation 1: y = mx + b

Substituting x = -0.8, y = -0.6 into Equation 1:

-0.6 = m*(-0.8) + b

Simplifying further, we can solve for m and b using the given values and determine whether the point is a solution.
