What is the slope?

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x (rise/run). It can be positive, negative, zero, or undefined.

Front

Solve for n: 6 - (8 - 4n) = 2(2n - 1)

Back

All real solutions

Front

What is y=mx+b called?

Back

Slope-intercept form, which is a way to express a linear equation where m is the slope and b is the y-intercept.

Front

Write the equation of the line with slope = 5 and passing through the point (3, -5)

Back

y = 5x - 20

Front

What does the term 'y-intercept' refer to?

Back

The y-intercept is the point where a line crosses the y-axis, represented by the value of y when x = 0.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

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

Back

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

Front

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

Back

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

Front

What does it mean for a line to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for a line to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1, meaning they intersect at a right angle.
