y-intercept =

Answer 1

in y = mx + b form, the y intercept is the number in the b position.

y = mx + b
y = -7x + 1.....now what number is in the b position ??

Answer 2

One is in the B Position, But I still dont Understand this? Can you explain it more?

Answer 3

the y intercept is where the line crosses the y axis....also, the answer would be (0,1) because your points are set up like (x,y).

Now if you were asked to find the x intercept (where the line cross the x axis) you would take your equation and sub in 0 for y
y = -7x + 1
0 = -7x + 1
7x = 1
x = 1/7......so you x intercept (put into a decimal) would be (0.14,0)

does that help any ?

Answer 4

Yes I understand it now, Thank you!
