If y = 1/2x + b, what is the y intercept?

Question

I need help on my homework.

Answer 1

It's impossible to know the exact answer without knowing what B equals. In a linear equation in slope-intercept form, (y = mx + b), the B value will be the y-intercept. So, here the coordinates would be (0, b). If you had a set of coordinates, you could plug the y value as y and the x value as x giving you b as the variable to solve for.
