Slope intercept form from a graph

Front

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

Back

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

Front

In the equation y = 4x + 3, what does the number 4 represent?

Back

The number 4 represents the slope of the line.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form.

Front

How do you find the slope from a graph?

Back

The slope can be found by selecting two points on the line and using the formula (y2 - y1) / (x2 - x1).

Front

What is the y-intercept of the equation y = -2x + 1?

Back

The y-intercept is 1.

Front

In the equation y = 6x + 10, what does the number 6 represent?

Back

The number 6 represents the slope of the line.

Front

How can you determine the equation of a line from a graph?

Back

Identify the slope and the y-intercept from the graph, then use the slope-intercept form y = mx + b.

Front

What is the slope of the line represented by the equation y = -3x - 1?

Back

The slope is -3.

Front

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

Back

A slope of 0 indicates that the line is horizontal.

Front

What does a negative slope indicate about the direction of a line?

Back

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