Answer:

The answer to your question is (-1, 4) The lines cross in one point so they have only one solution.

Step-by-step explanation:

Data

Equation 1 x - 4y = -17

Equation 2 y = 4x + 8

Solve for y

Equation 1 y = -x/-4 - 17/-4

y = x/4 + 17/4

Equation 2 y = 4x + 8

See the graph below

These lines cross in point (-1, 4), so that is the only one solution.

If the lines were the same line they would have infinite solutions

So you will use slope formula which is m = (y2 -- y1) / (x2 -- x1)

-1 minus -7=6

13 minus -8=21

Remember it changes to a positive Keep,Change,Change

So its 6/21

Or 1/4

Answer:

Step-by-step explanation:

A square has four sides and the area is 10,000 m^2. Area is determined by multiplying two sides. In this case, you can divide by two to get 5000, then again by 2 to get 2500. Each side/dimensions are 2500m^2
