Writing Equations Given Slope & y-intercept

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

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

If the slope (m) is -2 and the y-intercept (b) is 5, what is the equation of the line?

Back

y = -2x + 5

Front

What does 'b' represent in the equation y = mx + b?

Back

The 'b' represents the y-intercept of the line.

Front

Identify the slope and y-intercept in the equation y = 2x - 3.

Back

Slope: 2, y-intercept: -3.

Front

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

Back

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

Front

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

Back

The slope of the line y = 4 is 0.

Front

If the slope is 1/2 and the y-intercept is -1, what is the equation of the line?

Back

y = (1/2)x - 1

Front

What is the meaning of a negative slope?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.
