Graphing Lines & slope

Front

What is the Point-Slope form of a linear equation?

Back

The Point-Slope form is given by the equation: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

How do you calculate 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 are x- and y-intercepts?

Back

The x-intercept is the point where the line crosses the x-axis (y=0), and the y-intercept is where the line crosses the y-axis (x=0).

Front

What is the slope of the line that passes through the points (10, 1) and (5, 2)?

Back

The slope is -1/5.

Front

Write the equation of the line in Point-Slope form that goes through the point (10,5) with a slope of -3.

Back

y - 5 = -3(x - 10).

Front

What is the slope of the line that passes through the points (-1,-9) and (5,-6)?

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates that the line is horizontal.

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates that the line is vertical.
