Can someone help me put this in slope-intercept form with steps?

2x+3y = -1

Answers

Answer:

Step-by-step explanation:

basically here we wanna get y by itself

2x + 3y = -1

subtract 2x from both sides

3y = -2x -1

then to get y by itself we have to divide everything by 3

y = -2/3x - 1/3

this is your equation in slope intercept form

hope this helps <3

Answer: y= -2/3 x -1/3

Explanation:

3y= -2x-1 (subtract 2x from 3y and transfer it to the other side)

y= -2x/3 -1/3 (divide 3 on both sides to leave y alone)

Final Answer: y= -2/3 x -1/3 (y equals to negative two-third x minus one-third)

Please help

Answers

Answer:7 2/4

Step-by-step explanation:

Alright let’s go step by step for this:

1.) 6 1/4 - 1 1/4 = 5

2.) If he can run 1 1/4 miles before needing a break you would have to divide that number into the subtracted number from above

5 ÷ 1 1/4

3.) simplify the equation

5 ÷ 1.25

4.) Then divide

5 ÷ 1.25 = 4
