Jordon Webb · Answer 1

y=7x

Step-by-step explanation:

y=ax+b

put (x, y) = (1,7), (0,0), (-1,-7)

when (0,0)

0=b

y=ax, put (1,7)

a=7

*If you want to check again, also put (-1,-7)

So, y=ax+b equal y = 7x

Mercedes Cobb · Answer 2

y = 7x

Step-by-step explanation:

Slope: (7-0) / (1-0) = 7

y-intercept is obviously 0

y = 7x + 0

y = 7x
