Solve the following Systems of Equations by Substitution or Elimination y = -2x

7x - 8y = -23

(4, -7)

(4, 1)

(-3, 5)

(-1, 2)

Infinite Solutions

No Solution

(-1,2)

Step-by-step explanation:

y = -2x (1)

7x - 8y = -23 (2)

Substituting the value of y in eqn.(1) into eqn (2);

7x - 8(-2x) = -23

7x + 16x = -23

23x = -23

x = -1

y = -2(-1) = 2.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
