Answer:

Graph D

Step-by-step explanation:

For graph A)

Equation would be: y = 2x + 1

For graph B)

Equation would be: y = 2x - 1

For graph C)

Equation would be: y = -2x - 1

For graph D)

Equation would be: y = -2x + 1

Hope this helps!

answer : D

steps :

graph the line using the slope and y-intercept, or two points.

slope: −2 (down 2, right 1)

y-intercept: (0,1) (where the line intercepts the y axis)

your points for your line:

$\left[\begin{array}{ccc}x&y\\0&1\\1&-1\end{array}\right]$

solution : the graph in answer D.

hope this helps !

Look at the graph shown:

NNADVOKAT [17]

We are going to base the answer off of the y=mx+b form where m represents slope and b represents the y-intercept.

First, we know that b must be -1 because the line hits the y-axis when y is -1
So this leaves us with either the first or second choice

Then we choose two points to find the slope. I am using (0,-1) and (1,2). If you count the boxes, the y-value increases by 3 as the x-value increases by 1. So the slope is 3/1 or 3.

So then we know the answer is y=3x-1
