Question

x + y = -1
2x-y=-14

Answer 1

What is the question? Solve the system of equations?

Answer 2

you need to use both equations to solve for x and y I'm assuming?

Answer 3

you can re write one expression to in terms of either x or y and then plugin that value into the second equation to find one variable.

Answer 4

\[y = -1-x \rightarrow 2x - (-1-x) = -14\]

Answer 5

estimate the solution to the inear system graphically
x+y=-1
2x-y=-14

Answer 6

linear

Answer 7

Easy: Find the x and y intercepts for each equation such as

Answer 8

y intercept (x=0) and x intercept (y=0)

Answer 9

for example, on the first equation

Answer 10

x+y =-1
y int (x=0)
0+y=-1
y = -1 (plug this coordinate into your graph)
then x int (y=0)
x+0=-1
x=-1 (plug this into your graph)
Now repeat the same process for the second equation

The coordinates for the first equation are (0,-1) and (-1,0)
