What is the slope of the line 6x + 8y = 12?
Margaret [11]

Answer:

The slope is -3/4

Step-by-step explanation:

6x + 8y = 12

Write the equation in slope intercept form  y = mx+b where m is the slope

Subtract 6x from each side

6x-6x + 8y = -6x+12

8y = -6x+12

Divide each side by 8

8y/8 = -6x/8 +12/8

y = -3/4x +3/2

The slope is -3/4

Solve −2x2 +3x − 9 = 0.
Dmitry_Shevchenko [17]
I assume you are asking to solve:

-2x^2 + 3x - 9 = 0

So first, this equation does not have real roots.

It only has 2 complex roots.

The roots are: 

3/4 * (1-i√7) and 3/4 * (1+i√7)
