Put this equation into slope- intercept form. -2x + 3y = 9​
AveGali [126]

Answer:

y = 2/3x + 3

Step-by-step explanation:

In order to put it in slope intercept form (y = mx + b), y needs to be isolated.

Add 2x to both sides:

-2x + 3y = 9​

3y = 2x + 9

Then, divide both sides of the equation by 3.

3y = 2x + 9

y = 2/3x + 3 is the equation in slope intercept form

Find the difference between 4/11 of 2½ and 3/4​
Lunna [17]

Answer:

4/11 of 2 1/2 = 4/11 * 5/2 = 20 / 22 = 10/11

a common denominator of 11 and 4 is 44

So 40 / 44 - 33 / 44 = 7/44

Check 4/11 * 2.5 = .909

3/4 = .75    

difference = .909 - .750 = .159

7/44 = .159
