(MCA) 4.3 Graphing and Writing linear equations in Slope-int.

Front

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

Back

The y-intercept is 5.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

The slope m is calculated as m = (y2 - y1) / (x2 - x1).

Front

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

Back

The slope is -1.

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

If a line has a slope of -3, what does this indicate about the line's direction?

Back

The line decreases as it moves from left to right.

Front

What is the equation of a line with a slope of 4 and a y-intercept of 3?

Back

The equation is y = 4x + 3.

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

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

Back

A slope of 0 indicates a horizontal line.

Front

What is the graphical representation of the equation y = 3/2x + 3?

Back

The graph is a straight line with a slope of 3/2 and a y-intercept of 3.
