# 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?

Oct 9, 2017

You have

$y = \frac{9}{8} x + 5 \to \left(1\right)$
$y = - 4 \to \left(2\right)$

Use (2) in (1) $\implies$

$- 4 = \frac{9}{8} x + 5$

$\frac{9}{8} x = - 9$

$x = - 8$

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