STAAR Review 2.1

Front

What is the Slope-Intercept Form of a linear equation?

Back

The Slope-Intercept Form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope (m) represent in a linear equation?

Back

The slope (m) represents the rate of change of y with respect to x, indicating how steep the line is.

Front

How do you identify the y-intercept (b) in the equation y = mx + b?

Back

The y-intercept (b) is the value of y when x = 0, which is the point where the line crosses the y-axis.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you convert the equation 2x + 3y = 6 into slope-intercept form?

Back

To convert, solve for y: 3y = -2x + 6, so y = -2/3x + 2.

Front

What is the slope of the line represented by the equation y = 4x + 3?

Back

The slope of the line is 4.

Front

If a line has a slope of -1/3, what does this indicate about its direction?

Back

A slope of -1/3 indicates that the line descends from left to right.

Front

What is the equation of a line with a slope of 3 and a y-intercept of -1?

Back

The equation is y = 3x - 1.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope is calculated using the formula m = (y2 - y1) / (x2 - x1).
