Final answer:
The slopes of the linear equations are -3 for equation A, 0.74 for equation B, and -2 for equation C. To solve for x and y values, methods like substitution and elimination would be used on the provided system of equations, which is not included.
Step-by-step explanation:
To solve a system of linear equations and find the x-value and y-value of the solution, you typically use methods such as substitution, elimination, or graphing. Unfortunately, the actual system of equations is not provided in the question, so I can't give a specific solution. But generally, you would solve for one variable in terms of the other using one equation and then substitute this expression into the other equation. After finding one variable, you substitute it back into one of the original equations to find the other variable.
To identify the slope of a linear equation in the form y = mx + b, m represents the slope. So, for the equations mentioned in Practice Test 4 Solutions:
- A. y = -3x - The slope is -3.
- B. y = 0.2 +0.74x - The slope is 0.74.
- C. y=-9.4 - 2x - The slope is -2.
As all three equations are linear, they all have slopes and are of the form y = a + bx, where b is the slope, and a is the y-intercept.
