and y-intercept of a
straight-line graph
determining a linear

slope-intercept form
Many relationships can be modelled by the graph of a straight line.
solving problems using
•
For example, a farmer purchases chicken feed pellets by mass, yet
equations in slope-
intercept form
dispenses the feed by volume. When the farmer analyses the feeding
of chickens, the relationship between the volume of feed pellets in
a dispenser and the mass of the feed may be modelled by a linear
equation. Linear equations can be written in different forms. Each
form can provide specifi c information about the graph.
