Math-Moving Straight Ahead

Front 1

coefficient

Back 1

a number that is multiplied by a variable in an equation or expression

Front 2

constant term

Back 2

a number in an equation that is not multiplied by a variable or an amount added or subtracted from the terms involving variables

Front 3

coordinate pair

Back 3

a pair of numbers of the form (x,y) that gives the location of a point on the coordinate plane

Front 4

function

Back 4

a relationship between two variables in which the value of one variable depends on the value of the other variable

Front 5

intersecting lines

Back 5

lines that cross or intersect

Front 6

linear function

Back 6

the relationship between distance and the time is a function and the distance is a function of time

Front 7

linear relationship

Back 7

a relationship in which there is a constant rate of change between two variables; for each unit increase in one variable, there is a constant change in the other variable

Front 8

origin

Back 8

the point where the x- and y- axes intersect on a coordinate graph

Front 9

point of intersection

Back 9

the point where two lines intersect

Front 10

properties of equality

Back 10

for all real numbers a, b, and c:
addition: if a=b then a+c=b+c
subtraction: if a=b then a-c=b-c
multiplication: if a=b then a*c=b*c
division: if a=b and c≠0 then a/c=b/c

Front 11

rise

Back 11

the vertical change between two points on a graph

Front 12

run

Back 12

the horrizontal change between two points on a graph

Front 13

scale

Back 13

the distance between two consecutive tick marks on the x- and y- axes of a coordinate grid

Front 14

slope

Back 14

the number that expresses the steepness of a line

Front 15

x-intercept

Back 15

the point where a graph crosses the x-axis
