Reflecting Points and Line Equations

Front

What is the equation of a line with a negative slope that crosses the y-axis at 3?

Back

y = -x + 3

Front

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

Back

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

Front

What is the slope of the line that passes through the points (3, 7) and (7, 2)?

Back

Slope = -\frac{5}{4}

Front

What is the unit rate if a car travels 60 miles in 1 hour?

Back

60 miles/1 hour

Front

What is the slope of a line that is vertical?

Back

Undefined

Front

What is the slope of a line that is horizontal?

Back

0

Front

What is the slope of the line that passes through the points (2, 4) and (6, 12)?

Back

Slope = 2

Front

What does a slope of -1 indicate about a line?

Back

The line decreases at a 45-degree angle.

Front

What is the general form of the equation of a line?

Back

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 mean?

Back

For every 1 unit increase in x, y increases by 3 units.
