How do you find the slope from a table of values?

Back

To find the slope from a table, use the formula m = (y2 - y1) / (x2 - x1) using two points (x1, y1) and (x2, y2) from the table.

What is the equation of a vertical line?

Back

The equation of a vertical line is x = a, where 'a' is the x-coordinate of any point on the line.

Front

What is the equation of a horizontal line?

Back

The equation of a horizontal line is y = b, where 'b' is the y-coordinate of any point on the line.

How do you write the equation of a line given two points?

Back

To write the equation of a line given two points, first find the slope (m) using the two points, then use the point-slope form y - y1 = m(x - x1) to find the equation.

Front

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

Back

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