PRACTICE TEST 4--Multiple Representations of Linear Eq

Front

What is the Y-Intercept?

Back

The Y-Intercept is the point where a line crosses the Y-axis, represented as (0, y).

Front

How do you find the Y-Intercept using CUTBACK?

Back

To find the Y-Intercept using CUTBACK, set x=0 in the equation and solve for y.

Front

What does the equation y=4 represent graphically?

Back

The equation y=4 represents a horizontal line that crosses the Y-axis at (0, 4).

Front

What does the equation x=4 represent graphically?

Back

The equation x=4 represents a vertical line that crosses the X-axis at (4, 0).

Front

How do you determine which equation matches a graph?

Back

To determine which equation matches a graph, analyze the slope and intercepts of the graph and compare them to the equations.

Front

What is the slope of the equation y=3x-5?

Back

The slope of the equation y=3x-5 is 3, indicating that for every 1 unit increase in x, y increases by 3 units.

Front

What does the equation y=-4 represent graphically?

Back

The equation y=-4 represents a horizontal line that crosses the Y-axis at (0, -4).

Front

What does the equation x=-4 represent graphically?

Back

The equation x=-4 represents a vertical line that crosses the X-axis at (-4, 0).

Front

How do you find the equation that matches a table of values?

Back

To find the equation that matches a table of values, identify the pattern in the x and y values and derive the linear equation.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is y = mx + b, where m is the slope and b is the Y-Intercept.
