Answer:

one number is 8 and the other number is 4.

Step-by-step explanation:

x - y = 4 Solution:

x + y = 12

x  - y =   4

Add the two equations together:

2x = 16

Divide both sides by 2:

x = 8

Solve for y:

Use equation 1 substituting for x:

x + y = 12

8 + y = 12

Subtract 8 from both sides:

y = 4

Answer:

one number is 8 and the other number is 4.

8 + 4 = 12

8 - 4  =  4

Hope this helps!

Answer:

y=2.5x

Step-by-step explanation:

To get the equation in y = mx + b format, we need to find m and b, the slope and y-intercept.

To find the slope, we need two points on a graph, which we have.

First, the slope

The formula for slope is

\frac{y2-y1}{x2-x1}

Our points, (6, 15) and (2, 5)

Plugging into our equation:

\frac{15 - 5}{6 - 2}, which is 10 divided by 4, which is 2.5

Our equation now:

y=2.5x+b

To find our b, we need to plug in one x value.

(6, 15) are our pair of points.

6 = x

15 = y

15 = 6(2.5) + b  =>

15 = 15+b  =>

b = 0

If b is 0, then we don't need to include b.

Our equation is y=2.5x
