Linear Equations Practice

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

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

Back

The slope of the line.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept of the line y = 3x + 5?

Back

The y-intercept is 5.

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, 2) with a slope of 4?

Back

y = 4x + 2.

Front

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

Back

The slope is -1.

Front

How do you convert the equation y = 2x + 1 to standard form?

Back

2x - y = -1.

Front

What is the point-slope form of a line?

Back

y - y1 = m(x - x1), where (x1, y1) is a point on the line.
