Graph the line y=-3x

Mathematics

Step-by-step explanation: Let's graph the equation y = -3x using its slope and y-intercept. The problem here is that our equation doesn't match up quite so well with the formula y = mx + b

Our slope or <em>m</em> which is represented by the coefficient of the x-term is clearly -3. However, you might be asking what is our y-intercept or <em>b</em>. Well, y = -3x can be thought of as y = -3x + 0. So you can now see that our <em>b</em> or y-intercept equals 0.

To graph the line, we start with the y-intercept. So our first point is a 0 on the y-axis and we call that point A. When the slope is a integer, you can change it to a fraction by putting it over 1. So our slope of -3 can be thought of as -3/1.

From point A, we would go down 3 units and over 1 unit to plot point B. Now we can connect points A and B like I did in the picture and we have our line.

Answer:

Step-by-step explanation:

Graph y = -3x.  Start at the origin (0, 0).  Place a dark dot there.  Now, starting with your pencil point on that dot, move 1 space to the right and from this new point move 3 spaces down.  Place a dark dot at this new point.

Now draw a straight line through both dark dots.  This is the desired graph.

Answer: 39.2

Check out the attached image

============================================================

Explanation:

Draw out the triangle or use the diagram provided by your teacher. It should look something similar to what I've attached. 

Let m = length of side XZ

We are given that
angle Y = 75 degrees
angle Z = 67 degrees
which are the green angles shown in the diagram

Use the fact that the three angles (X,Y,Z) add to 180 degrees to find angle X
X+Y+Z = 180
X+75+67 = 180
X+142 = 180
X+142-142 = 180-142
X = 38

Now use the law of sines to find m
sin(X)/YZ = sin(Y)/XZ
sin(38)/25 = sin(75)/m
m*sin(38) = 25*sin(75)
m = 25*sin(75)/sin(38)
m = 39.22309 <<<--- make sure your calculator is in degree mode
m = 39.2

So XZ is roughly 39.2 feet in length

Please help, I will give brainliest. I am struggling badly.

Answer:

B because the line crosses the y axis at 4  and the slope will be -1 because the line is going downhill which therefore makes it negative

hope it helps:)

In this figure, ∠a and ∠b are A. complementary. B. vertical. C. equal. D. supplementary.
Aleks [24]
Sorry I don't see a picture. But...

If they add up to 90 degrees, they are complimentary

If they add up to 180 degrees ( a straight line) they are supplementary.

If they are vertical, they will be on either side, like two v's ><
