Find The Equation of the Line

Front

What is the slope-intercept form of a line?

Back

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

How do you find the slope between two points?

Back

The slope (m) between two points (x1, y1) and (x2, y2) is calculated using the formula m = (y2 - y1) / (x2 - x1).

What does the y-intercept represent in a linear equation?

Back

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

What is the equation of a line that passes through the point (0, 6)?

Back

The equation is y = 6, which is a horizontal line.

Front

If the slope of a line is 3, what does this mean?

Back

A slope of 3 means that for every 1 unit increase in x, y increases by 3 units.
