What is the slope of the line shown in the graph?<br> A 3/2<br> B 2/3<br> C -3/4<br> D - 2/3
goldenfox [79]

Answer:

D. -2/3

Step-by-step explanation:

Since it is going down, it is negative

Think of this: Rise/Run

In this case, rise is when you are going up or down the graph

Run is when you are going to the right of the graph

Let's use 2 points (0,3) and (3,1)

Since you are going three points to the right we are going to put 3 in for run

You are going 2 places down, so we are going put -2 in for rise

This gives us -2/3

Another way to do this is (1-3)/(3-0) = -2/3

Each statement describes a transformation of the graph of y = x. Which statement correctly describes the graph of y = x + 7? A.
rosijanka [135]
<h3>Answer: choice A, graph is moved 7 units up</h3>

The plus 7 at the end will shift the graph 7 units up. Replace y with f(x).

Then we have g(x) = f(x) + 7. Adding 7 to y = f(x) will increase the y value by 7.
