Question | Answer |
---|---|
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. |
