Question

Line A (y= x + 2) is transformed into Line B (y=3x + 1) . which best describes the new slope and y-intercept? the slope is ___, and the line is shifted ____. a) steeper b) flatter -----a) upward b) downward

Answer 1

steeper, downward

1) Analyzing both functions, we have y=x+2 becoming under transformations y=3x+1

2) So we can write that the slope is steeper since the slope has become 3 times greater than the original slope, m=1.

And the line is shifted downward since that +1 is below +2.

3) Hence, the answer is steeper, downward
