Line A (y = x + 2) is transformed into Line B (y=3x+1). Which best describes the new slope and y-intercept?

Alona [7]

Answer:

The slope is steeper and the line is shifted downwards.

The y-intercept is shifted downwards.

Step-by-step explanation:

We proceed to demonstrate the transformation from the line A to line B:

1) $y = x + 2$ Given.

2) $y = 3\cdot x + 6$ Vertical dilation.

3) $y = 3\cdot x +1$ Vertical shift of the line in 5 units in the -y direction/Result

Hence, the answer is:

The slope is steeper and the line is shifted downwards.

The y-intercept is shifted downwards.

What does the graph of y=(x + 2)(x + 1)(x - 3)2 do near the point (3,0)?

IRINA_888 [86]

Check out the graph below. We see that (3,0) is a root or x intercept. More specifically, the graph only touches the x axis at this point, rather than cross over (in contrast to a root like (-2,0) ). We say that the root here is of multiplicity 2. The multiplicity is due to the exponent of 2 over the (x-3) factor.

You can also say that the graph is decreasing on the left side of (3,0) and then it bounces off the root x = 3 to increase afterward. In this region, the graph never goes below the x axis.
