What is the initial step when solving a system of equations graphically?

• Find the intersection point of the lines.

• Plot the graph of each equation.

• Substitute values to check the solution.

• Convert equations to slope-intercept form.

To find the x-intercept of a linear equation, what value should be set to zero?

• The x-value.

• The y-value.

• The slope.

• The constant term.

When graphing a linear equation using the slope-intercept form (y = mx + b), what does the 'rise' component of the slope (m) represent?

• The horizontal change between two points.

• The y-intercept of the line.

• The vertical change between two points.

• The x-intercept of the line.

When graphing a linear equation with a slope of -4/3, starting from a point, how should you move to find the next point?

• Move 4 units up and 3 units right.

• Move 4 units down and 3 units right.

• Move 4 units up and 3 units left.

• Move 4 units down and 3 units left.

What does it mean if the lines of a system of two linear equations are parallel?

• The system has one unique solution.

• The system has no solution.

• The system has infinitely many solutions.

• The system has two solutions.
