Front

What type of line is represented by the equation y = 10?

Back

Horizontal line.

Front

How do you find the slope of a line given two points?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What are the x and y intercepts of the equation 4x - 10y = 20?

Back

x-intercept = 5, y-intercept = -2.

Front

What is the equation of a line with a slope of -4/5 and a y-intercept of 3?

Back

y = -\frac{4}{5}x + 3.

Front

How do you identify the x-intercept of a line?

Back

Set y = 0 in the equation and solve for x.

Front

How do you identify the y-intercept of a line?

Back

Set x = 0 in the equation and solve for y.

Front

What is the slope of a line that rises 4 units for every 3 units it runs?

Back

Slope = \frac{4}{3}.

Front

What does a vertical line look like in an equation?

Back

An equation of the form x = a, where 'a' is a constant.

Front

What does a horizontal line look like in an equation?

Back

An equation of the form y = b, where 'b' is a constant.

Front

How do you convert the standard form of a linear equation to slope-intercept form?

Back
