Question

How do you solve the system of equations by graphing and then classify the system as consistent or inconsistent `y= 9/8x+5` and `y= -4`?

Answer 1

You have

`y = 9/8x+5 ->(1)`
`y = -4->(2)`

Use (2) in (1) `=>`

`-4 = 9/8x+5`

`9/8x = -9`

`x = -8`

Substitute graph{9/8x+5 [-10.5, 5.5, -5.2, 5]}
