Front

What is the slope of the line that passes through the points (9, -5) and (8, -5)?

Back

0

Front

Write the equation of the line that has a slope of -3/2 and passes through the y-intercept of 4.

Back

y = -3/2x + 4

Front

The table below represents the number of miles, y, that the satellite Space Explorer flies in x hours. Find the rate of change in miles per hour if it flies 1800 miles in 1 hour.

Back

1800

Front

The satellite Space Explorer flies 35200 miles in 11 hours. Find the rate of change of miles per hour.

Back

3200

Front

Define the term 'slope' in the context of a linear equation.

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x.

Front

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

Back

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

Front

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

Back

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 descends from left to right.

Front

What is the y-intercept of a line?

Back

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