Answer: Hello there!

In your graph you can see two things, first, your function only has negative values (and decreasing, so it never is positive), and second, it intersects the x-axis in x = 3.

The first thing says to us that we should discard the second and third options, because they allow positive values for y (you can evaluate them in x = 10 for example, and see that y is positive).

Now we get the first and fourth options to analyze:

1) y = -\frac{1}{2} Ix-3I

2) y = -\frac{1}{2} IxI - 3

if you evaluate this functions in x = 3, y should be 0.

in the first equation this is trivial, and in the second you got:

y = 3/2 - 3 = -3/2

so this equation didn't give us 0.

Then the correct answer is the first option.

Answer:

Step-by-step explanation:

line 1  m=y2-y1 / x2-x1  [formula for slope ]

m= 0 - (-3) / 8-(-4)

m= 3 /12      

m= 1/4  slope of line 1

line2  

m = 2-6 / 0-(-1)

m = -4 / 1

m = -4  slope of line 2

line 3

m = -4 - (-7)  / -3 -  6

m = 3 / -9

m = - 1/3  slope of line 3

lines 1 & 2   perpendicular b/c they are reciprocals with a sign change :)

lines 1 & 3     neither.. differet slopes and not reciprocals

lines 2 & 3  perpendicular  b/c they are reciprocals with a sign change :)

Someone please tell me how to work out this type of problem i completely forgot
fenix001 [56]

Answer:

Plug the x-values into the equation to get the y values. This will give you coordinates that you can graph a line with.

Step-by-step explanation:

For x = -5:  y = -3 - 2 * (-5) = 7, so the coordinates are (-5, 7)

For x = -2:  y = -3 - 2 * (-2) = 1, so the coordinates are (-2, 1)

(Etc.)

Then, plot these coordinates and draw a line through them to complete the graph.
