Solve the system of equations.
-3x +y = 2
70 – 8y = 1
Solution:
y =

x = -1, y = -1.

Step-by-step explanation:

-3x +y = 2

7x – 8y = 1

We can use the  elimination method to solve these:

Multiply the first equation by 8:

-24x + 8y = 16

Now add this to the second equation:

-17x -8y + 8y = 17

-17x = 17

x = -1.

Plug x = -1 into the first equation:

-3(-1) + y = 2

3 + y = 2

y = -1.

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.
