Front

What is slope-intercept form?

Back

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

Front

How do you convert an equation to slope-intercept form?

Back

To convert an equation to slope-intercept form, solve for y in terms of x.

Front

What does the variable 'm' represent in the equation y = mx + b?

Back

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

Front

What does the variable 'b' represent in the equation y = mx + b?

Back

In the equation y = mx + b, 'b' represents the y-intercept of the line.

Front

What is the slope of a line that is perpendicular to a line with slope 3?

Back

The slope of a line that is perpendicular to a line with slope 3 is -1/3.

Front

How do you find the equation of a line given a point and a slope?

Back

Use the point-slope form: y - y1 = m(x - x1), where (x1, y1) is the point and m is the slope.

Front

What is the relationship between parallel lines in terms of slope?

Back

Parallel lines have the same slope.

Front

What is the relationship between perpendicular lines in terms of slope?

Back

Perpendicular lines have slopes that are negative reciprocals of each other.

Front

Convert the equation 2x + 3y = 6 to slope-intercept form.

Back

y = -rac{2}{3}x + 2.

Front

What is the slope of the line described by the equation y = -4x + 20?

Back

The slope of the line is -4.
