Graphing Equations - Test - Retake

Front

In the linear equation y = mx + c, what does the letter 'm' represent?

Back

The letter 'm' represents the slope of the line.

Front

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

Back

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

Front

How do you determine the slope from the equation y = 3x + 4?

Back

The slope is the coefficient of x, which is 3.

Front

What is the y-intercept in the equation y = -2x + 5?

Back

The y-intercept is 5, which is the value of y when x = 0.

Front

If a line has a slope of 0, what does this indicate about the line?

Back

A slope of 0 indicates that the line is horizontal.

Front

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

Back

The slope of the line is 4.

Front

How can you convert the equation 2x + 3y = 6 into slope-intercept form?

Back

To convert it, solve for y: 3y = -2x + 6, then y = -2/3x + 2.

Front

What does a negative slope indicate about a line on a graph?

Back

A negative slope indicates that the line is decreasing from left to right.

Front

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

Back

The slope of the line is -1.

Front

In the equation y = mx + c, what does 'c' represent?

Back

The letter 'c' represents the y-intercept of the line.
