Constant increase or constant decrease situations

What is a linear function? Any function whose graph is a line.
Consider the equation 10x+12y=60. What is the slope of the line? -5/6
Give an equation for a line with a slope of 5. y=3+5x
Does the formula an=2n+6 generate an arithmetic sequence? Yes, because there is a constant difference of 2 between the terms.
Give an equation for the line parallel to 9x+4y=22 that contains the point (1,-6). y+6=-9/4(x-1)
State the Point-Slope Theorem. If a line contains (x1,y1) and has slope m, then it has equation y-y1=m(x-x1).
what is an arithmetic sequence? A sequence with a constant difference between successive terms.
