Linear Equations Test

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Two lines are perpendicular if the product of their slopes is -1.

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form.

To find the x-intercept, set y = 0 in the equation and solve for x.

The average rate of change is calculated as (f(b) - f(a)) / (b - a) over the interval [a, b].

The equation is y = 3x - 1.

Rearrange the equation Ax + By = C to solve for y, resulting in y = (-A/B)x + (C/B).

The slope indicates the steepness and direction of the line; a positive slope rises, while a negative slope falls.

For the equation Ax + By = C, the slope is -A/B.
