Real Number Whole Numbers:0,1,2,3,4,5,6,7,8,9,10,etc. Counting Numbers:1,2,3,4,5,6,7,8,etc. Natural Numbers:which is whole or counting numbers depends on the topic Integers:-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10,etc.
y=mx+b , where m is the slope, and b is the y -intercept
the y -intercept is where the line intersects the y-axis so b = -2
the slope m= y(rise) /x(run) = 6/-5 = -6/5 ( to find the slope you have to know how to get from any point on the line to another point on the same line; start at point (0,-2) go up 6(y-rise) and to the left 5(x-run) at point (-5,4))
