Solve each system of equations using substitution. #4 is done for you.
son4ous [18]

Answer:

y = 5 and x = -3

Step-by-step explanation:

Given,

y = x + 8      ...............( equation 1 )  

x + y = 2      ...............( equation 2 )

Now,  by substituting the value of y in equation 2, we get;

⇒ x + x + 8 = 2

⇒ x = -3

and now, by substituting the value of x in equation 1, we get;

⇒ y = -3 + 8

⇒ y = 5

Find the slope of a line parallel to the line through the given points. P(-2, 4), Q(6, -2) 4/3 3/4 -3/4
Galina-37 [17]

Answer:

slope = - \frac{3}{4}

Step-by-step explanation:

Parallel lines have equal slopes thus the slope of a parallel line will be equal to the slope of PQ

To calculate slope m use the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = P(- 2, 4) and (x₂, y₂ ) = Q(6, - 2)

m = \frac{-2-4}{6+2} = \frac{-6}{8} = - \frac{3}{4}
