They get 2/3 because 2 divided by 3=2/3.
Y= -9x+5
The slope intercept formula is y=mx +b, where m is the slope and b is the y-intercept. We know that m is -9 because that’s the slope and b is 5 because the y-intercept is at (0, 5), meaning that’s where the line crosses the y-axis.
According to Google, yes.... any details, I have no idea, but I hope I helped in any way, haha
Good luck~~
