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 = 3x + 2?

Back

The y-intercept is 2.

Front

What is the graph of y = -x + 3?

Back

A straight line with a slope of -1 and a y-intercept of 3.

Front

How do you graph the equation y = (1/2)x?

Back

Start at the origin (0,0) and use the slope of 1/2 to plot points.

Front

What is the slope of the line represented by the equation y = 2x - 1?

Back

The slope is 2.

Front

Which graph represents the equation y = (2/3)x - 1?

Back

A straight line with a slope of 2/3 and a y-intercept of -1.

Front

What is the solution to the equation y = x - 2 when x = 4?

Back

y = 2.
