Discuss the Ideas

1. When a real-world situation can be modelled by a linear function, what do

the slope and vertical intercept usually represent?

The slope represents the rate of change; that is how one quantity changes

with respect to another quantity.

The vertical intercept usually represents the initial value in a context; for

example, the initial distance from a destination, or the volume of fuel in a full

tank.

2. When you are given the graph of a linear function, how can you determine

an equation that represents that function?

You need to determine the slope of the line and its y-intercept. You substitute

y = mx + b

the values in the equation form:

3. When you are given an equation of a linear function in slope-y-intercept

form, how can you quickly sketch the graph?

When an equation of a linear function in slope-intercept form is given, you

would use the value of the y-intercept and locate it on the graph, and then

continue to find the next point by apply the rise and run values.
