Answer:

Slope: 5/4 , y-intercept: -3/2

Step-by-step explanation:

use the formula: y = mx + b, m is the slope, b is the y-intercept

5x + 1 = 4y + 7

-4y = -5x + 6

y = 5/4x - 6/4

y = 5/4x - 3/2

6n + 9 = -3 - 21 - 6

$6n+9=-3-21-6$
subtract the numbers: $-3-21-6=-30$
$6n+9=-30$
subtract 9 from both sides
$6n+9-9=-30-9$
simplify
$6n=-39$
divide both sides by 6
$\frac{6n}{6}= \frac{-39}{6}$
$n= \frac{-13}{6}$
decimal $n=-6.5$
Hope this helps :)
