Linear Function Graphs

CONCEPTUAL

Mathematics›Algebra|Ages 12—14|ID: mt_WBdHkc2HTf

Recognise that a linear function produces a straight-line graph, understand the relationship between an equation of the form y = mx + c and its graphical representation, and interpret gradient and y-intercept in context

Mastery Evidence

Explain that changing m in y = mx + c alters the steepness and direction of the line
Identify the y-intercept of a line from its equation and from its graph
Determine whether a given equation will produce a straight line or a curve

Assessment Prompt

“If [child] sees the equation y = 2x + 3, can they explain what the graph will look like — including how steep it is and where it crosses the y-axis?”

8.EE.5Common Core State Standards for Mathematics

Graph proportional relationships

Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.

8.EE.6Common Core State Standards for Mathematics

Deriving slope and linear equations

Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

8.F.3Common Core State Standards for Mathematics

Linear and non-linear functions

Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s² giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
