Graphing Linear Equations y=mx+b

Front

What does 'b' represent in the slope-intercept form of a linear equation (y=mx+b)?

Back

The y-intercept, which is the point where the line crosses the y-axis.

Front

What does 'm' represent in the slope-intercept form of a linear equation (y=mx+b)?

Back

The slope (rate of change) of the line, indicating how steep the line is.

Front

What is the slope of the line represented by the equation y = 5x - 3?

Back

The slope is 5.

Front

What is the y-intercept of the line represented by the equation y = -2x + 4?

Back

The y-intercept is 4.

Front

Which equation represents a line with a slope of -3 and a y-intercept of 2?

Back

y = -3x + 2.

Front

How do you find the x-intercept of a linear equation?

Back

Set y to 0 and solve for x.

Front

What is the x-intercept of the equation y = 2x + 6?

Back

The x-intercept is -3.

Front

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

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

The line is vertical.

Front

What is the equation of a line that passes through the point (0, 0) with a slope of 4?

Back

y = 4x.
