Linear Equations Practice

Front

In the equation y = mx + b, what does the m represent?

Back

m represents the slope of the line.

Front

What is the slope in the equation y = 2x + 3?

Back

The slope is 2.

Front

The initial temperature recorded on Monday was 45 degrees. The temperature decreases 2 degrees per hour. Which equation best represents this scenario?

Back

y = -2x + 45.

Front

Determine the equation of the line in the given graph: y-intercept is 4 and slope is -2.

Back

y = -2x + 4.

Front

What is the equation of the line shown in the graph with a slope of 1/2?

Back

y = 1/2x.

Front

What does the term 'y-intercept' mean in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.

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 standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What does it mean if a line has a slope of 0?

Back

A slope of 0 means the line is horizontal.

Front

What does it mean if a line has an undefined slope?

Back

An undefined slope means the line is vertical.
