Find the y-intercept of the line: 5x + 7y + 1 = 0

y intercept = -1/7

Step-by-step explanation:

Rearrange into the format y = mx + c, when c is the y intercept.

5x + 7y + 1 = 0

7y  = -5x - 1

Divide by 7

y = -5x/7 - 1/7

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
