Tom [10]

Answer:

3¼

Step-by-step explanation:

formula \frac{{y}^{2} - {y}^{1}  }{ {x}^{2} -  {x}^{1}  }

We take any of the two points shown in the question. I will take (-3, 1) and (1, 14).

x¹ = -3

y¹ = 1

x² = 1

y² = 14

Now, we sub these figures into the formula.

\frac{14 - 1}{1 - ( - 3)}

This leaves us with 14-1/1+3, which we can make into 13/4

13/4 = 3¼

What is the result of subtracting the second equation from the first?
dusya [7]

Answer: 11x-8y=-9

Step-by-step explanation:

For this exercise you need to remember:

1) The mulitplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

2) By definition, like terms contain the same variables with the same exponent.

Then knowing this, and given the equations:

8x - 4y = -4 and -3x+ 4y = 5

You must subtract the like terms, which means that you must subtract the numerical coefficients of each term.

Then, you get the result is:

8x - 4y = -4\\-3x+ 4y = 5\\...............................................\\8x-(-3x)-4y-4y=-4-5\\8x+3x-8y=-9\\11x-8y=-9
