Answer:

x +0y+0z = 400

-x +y+0z = 150

-8x +0y +z = 250

Step-by-step explanation:

The last column is the solution

The rest of the columns are the coefficients of the variables

x +0y+0z = 400

-x +y+0z = 150

-8x +0y +z = 250

Identify the X intercept and the yIntercept of the line 4x-2y=-12
sammy [17]

Answer:

X-intercept = -3 and y-intercept = 6

Step-by-step explanation:

We can start off by isolating the y term. To do that, we must add 2y to both sides to get

4x=2y-12

Now, we must add 12 to both sides and the y term will be all alone on the right side:

4x+12=2y

Now, to have only y on the right side, we must divide by 2 to get:

y=2x+6

In slope-intercept form, b is the y-intercept, and 'b' in this equation is 6. We have our y-intercept.

To find our x-intercept, y must be equal to zero. We can plug in that value for y and solve for x:

0=2x+6

We can start off by subtracting 6 from both sides to get:

2x=-6

We can then divide both sides to get x=-3 when y is equal to 0. Thus, we have our x-intercept.
