Slope Intercept Form (Final Practice)

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope (m) represent in the slope-intercept form?

Back

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

Front

What does the y-intercept (b) represent in the slope-intercept form?

Back

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

Front

How do you find the y-coordinate when given an x-coordinate in the equation y = -3x - 5?

Back

Substitute the x-value into the equation and solve for y.

Front

Given the equation y = 2x + 8.6, what is the y-value when x = 3?

Back

y = 2(3) + 8.6 = 14.6.

Front

What is the slope of the line represented by the equation y = 4/3x - 1?

Back

The slope is 4/3.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant.

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.
