Linear Functions and Equations

13. 2x+y=6 plot-ordered pair as a point in a number plane.

y= 6-2x horizontal axis-horizontal number line

14. 5x+y=7 origin-point of intersection at y & x on a coordinate

y=7-5x vertical axis-second number line

15. 3x+2y=8 x-axis-horizontal axis

y=-3/2x+4 y-axis-vertical axis

16.2x+5y=10 graph of ordered pair-(2,3)

y=-2/5x+2 coordinates- shown as pair of letters/numbers (2,3)

x-coordinate- position of coordinate according to x-axis

y-coordinate-position of coordinate according to y-axis

coordinate axes- y/x axes

coordinate plane- contains 2 perpendicular axes(x,y)

quadrants- quarter of a circle or its circumference

linear equation-relating to a line, straight direction

Graph of Equation-2 variables that consist of all points that are the
solution to equation.
