Writing Equations of Lines

Front

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

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept (b) is the value of y when x = 0.

Front

Write the slope-intercept form of the equation with a slope of 2 and a y-intercept of 5.

Back

y = 2x + 5

Front

Determine the slope and y-intercept from the equation y = -4x + 1.

Back

slope: -4, y-intercept: (0, 1)

Front

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

Back

b represents the y-intercept.

Front

Write the slope-intercept form of the equation with a slope of -1 and a y-intercept of 3.

Back

y = -1x + 3 or y = -x + 3

Front

If the slope of a line is 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If the slope of a line is undefined, what does that indicate about the line?

Back

The line is vertical.

Front

Convert the equation y = 3x + 2 to slope-intercept form.

Back

The equation is already in slope-intercept form: y = 3x + 2.

Front

What is the slope of the line represented by the equation y = 5?

Back

The slope is 0, indicating a horizontal line.
