If the equation of a line is written in the

form,

is the y-intercept.

The y-intercept is -1. The line crosses the y-axis at the point (0,-1).
Depends on where you are in the math book but this would be the most simple way.
n= number
sqar(-1) = i
A.
7 times number of cats=pay
if pay=49 then
7 times number of cats=49
divide both sides by 7
number of cats=7
da equaton can be
c=number of cats
7c=49
he fed 7 cats
B.
7c=49
divide both sides by 7
equality property of division
(7c)/7=49/7
math fact
(7/7)c=7
1c=7
identity property of division
c=7
identity property of multiplication
7 cats
C. 7 cats
