STAAR ALGEBRA 1 CATEGORY 2 PART 1

Front

What is the solution to a system of linear equations represented graphically?

Back

The solution is the point where the graphs of the equations intersect.

Front

How does shifting the graph of a function vertically affect its equation?

Back

Shifting the graph down by 'k' units results in the equation g(x) = f(x) - k.

Front

What is the slope of a line in the equation y = mx + b?

Back

The slope is represented by 'm' in the equation.

Front

How can you determine the slope from a linear equation in slope-intercept form?

Back

In the equation y = mx + b, 'm' is the slope.

Front

What does a slope of 2 indicate about a line?

Back

It indicates that for every 1 unit increase in x, y increases by 2 units.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by 'b' in y = mx + b.

Front

How can you identify the slope from the equation y = 2(x - 3) + 7?

Back

The slope is 2, as it is the coefficient of x in the equation.
