What is the slope of 2x+3y=15

Fynjy0 [20]

Note that the slope-intercept form is: y = mx + b

First, set the equation as such

2x (-2x) + 3y = (- 2x) + 15

3y = -2x + 15

Isolate the y. Divide 3 from both sides

(3y)/3 = (-2x + 15)/3

y = (-2/3)x + 5

-2/3 is your slope

hope this helps

Write the augmented matrix for each system of equations.

Fudgin [204]

We are given the equations: 

10x = 10

-5x - 8y = 9

Since we don't have a coefficient of y in the first equation, we will rewrite the first equation as:

10x + 0y = 10

Writing an Augmented matrix for the 2 equations:

10x + 0y = 10

-5x - 8y = 9

$\left[\begin{array}{ccc}10&0|&10\\-5&-8|&9\end{array}\right]$
