Writing Equations from Graphs B

Front

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

Back

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

Front

How do you identify the slope from the equation y = mx + b?

Back

The slope (m) is the coefficient of x in the equation.

Front

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

Back

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

Front

If a line has a slope of 4, what is the equation of the line that passes through the origin?

Back

The equation is y = 4x.

Front

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

Back

The slope is -1.

Front

How do you convert the equation y = 2x + 3 to slope-intercept form?

Back

It is already in slope-intercept form: y = 2x + 3.

Front

What is the equation of a line with a slope of -5/2 and a y-intercept of 3?

Back

The equation is y = -5/2x + 3.

Front

How do you find the y-intercept from the equation y = -2/3x - 3?

Back

The y-intercept is -3.

Front

What is the slope of the line represented by the equation y = 2/3x?

Back

The slope is 2/3.

Front

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

Back

A slope of 0 indicates a horizontal line.
