PLEASE HELP ITS IS IMPORTANT TOWARDS MY GRADE number 7 look below for the picture

Answer:
It's y=-2/7x+1/7 (fractions) because slope-intercept form is y=mx+b
Step-by-step explanation:
Your answer is y = -2/7x + 1/7
Firstly, remove 2x from each side, to bring it to the right side of the equation.
2x + 7y = 1 ---> 7y = -2x +1
Then, just divide it all by 7.
7y = -2x +1 ---> y = -2/7x + 1/7
You've got your answer!
