Graphing Linear Equations

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

Slope of the line.

Front

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

Back

Y-intercept of the line.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the y-intercept of the equation y = 2x + 3?

Back

3.

Front

What is the slope of the line represented by the equation y = -4x + 1?

Back

-4.

Front

Which graph represents the equation y = 1/2x - 2?

Back

Graph A.

Front

How do you graph a linear equation in slope-intercept form?

Back

Start at the y-intercept (b) on the y-axis, then use the slope (m) to find another point.

Front

What is the equation of a line with a slope of 3 and a y-intercept of -1?

Back

y = 3x - 1.

Front

If a line has a slope of 0, what type of line is it?

Back

A horizontal line.
