convert the equation 9x - 7y = -7
Answer: 7y = 9x + 7
I have to convert the equation 9x - 7y = -7
To slope intercept form
Answer: 7y = 9x + 7
y = (9/7) x + 1
To convert the equation 9x - 7y = -7, we want to isolate y on one side of the equation.
Step 1: Start by moving the 9x term to the other side of the equation by adding 9x to both sides:
9x - 7y + 9x = -7 + 9x
Simplifying:
18x - 7y = 9x - 7
Step 2: Move the 9x term to the left side of the equation by subtracting 9x from both sides:
18x - 9x - 7y = -7 - 9x
Simplifying:
9x - 7y = -7 - 9x
Step 3: Rearrange the equation to have y on the left side:
-7y = 9x - 7 + 9x
Simplifying:
-7y = 18x - 7
Step 4: Finally, divide both sides of the equation by -7 to solve for y:
y = (18x - 7) / -7
Simplifying further:
y = -18x/7 + 1
Therefore, the equation 9x - 7y = -7 can be converted to 7y = 9x + 7.
