Front

Slopes of perpendicular lines are...

Back

opposite reciprocals.

Front

Write the equation of the line in Point-Slope form that goes through the point (10,5) and has a slope of -3.

Back

y - 5 = -3(x - 10)

Front

Write in slope intercept form: 5x - 3y = -9

Back

y = (5/3)x + 3

Front

A line is parallel to y = 2x - 7. What is the slope of this line?

Back

Front

Find the slope between the two points (-12, 14) and (-6, -12).

Back

-13/3

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

m = (y2 - y1) / (x2 - x1)

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

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

Back

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

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

How do you determine if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
