Linear Relationship in Slope Intercept Form

Write an equation of the trend line in slope-intercept form.

Write an equation of the trend line in slope-intercept form.

A group of hikers is descending, and the elevation of several of the hikers after a certain number of minutes is shown in the scatter plot.

True or False:

The equation of the trend line is y = 2500x-125

• True

• False

A group of hikers is descending, and the elevation of several of the hikers after a certain number of minutes is shown in the scatter plot.

True or False:

The group of hikers descends about 250 feet every minute.

Hint: What's the unit rate, slope?

• True

• False

Match the scatter plot to the equation that could represent the equation of its trend line.

• y = 3x

• y=4x-2

• y = -x + 5

• y = -5x

• The relationship is not linear
