Identifying Slope and Y-Intercept

Front

What is the definition of slope in a linear equation?

Back

The slope is a measure of the steepness of a line, represented as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

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

Back

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

What is the y-intercept of a linear equation?

Back

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

How can you identify the slope from the equation y = mx + b?

Back

In the equation y = mx + b, 'm' represents the slope of the line.

How do you convert the equation y = 2 into slope-intercept form?

Back

The equation y = 2 can be rewritten as y = 0x + 2, indicating a slope of 0 and a y-intercept of 2.
