Relations & Linear Functions (7.10)

SOL 7.10 The student will

a) determine the slope, m, as rate of change in a proportional relationship between two quantities and write an equation in the form y=mxto represent the relationship;

b) graph a line representing a proportional relationship between two quantities given the slope and an ordered pair, or given the equationy=mx form wheremrepresents the slope as rate of change.

c) determine the y-intercept, b, in an additive relationship between two quantities and write an equation in the form y=x+b to represent the relationship;

d) graph a line representing an additive relationship between two quantities given the y-intercept and an ordered pair, or given the equation in the form y=x+b, where b represents the y-intercept; and

e) make connections between and among representations of a proportional or additive relationship between two quantities using verbal descriptions, tables, equations, and graphs.
