1. Name________________________________________________ Class_____ 19___A way to determine if a graph is a function using a straight line to see if it touches the graph more than one time. 9____Weight 16___Space enclosed by a 3 dimensional object, found by multiplying the area of the base of an object by it’s height 14___Writing an equation or a line of best fit given only points on a graph or table 10___The middle point of a line 7____A letter used for “m” (slope in an equation where there is no “b”. 1____“k” as in “k”x where the function is proportionate and the y intercept is always at the origin 20___The slope-intercept form of a linear equation 11___An equation of the form y=mx +b where the y intercept is not zero 12___The point (0,0) on a graph 13___When y and x are related as equals Example: y = x 3____An equation or graph where no two “x’ values are the same 5____y = mx + b written in the form f(x)=mx+b Example y =3m+4 is f(m) = 3m+4 4____An equation written in function notation form 15___When you write an equation or line of best fit from points that have a quadratic correlation ( a parabolic shape) 8____When you write an equation or line of best fit from points that have a linear correlation (straight line) 17___Where a graph crosses or touches the x axis 18___Where a graph crosses or touches the y axis 6____When y and x relate in an inverse manner: Example 2____When to variables relate to each other equally Example y = x Constant of Variation Direct Variation Function Function Rule Function Notation Inverse variation “k” as in “k”x Linear Regression Mass Midpoint Non Proportionate Origin Proportionate Regression Model Quadratic regression Volume X intercept Y intercept Vertical Line test y=mx+b
