x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.
(7,12)
5y+8=7y 2y=8 y=4
This cannot have an answer. "7y12" is not correct. If you put a plus before the twelve, this is how you solve it. y=m(slope)x(independant variable)+b(y intercept) 3x-7y+12 +7y 7y=3x-12 /7 /7 /7 y=3/7+1.714285 repeating 1.714285 repeating is the y intercept of there is a minus sign, just switch the positive on the y intercept.
