Question

Write and equation in slope intercept form from points (1,1)(1,5)

Answer 1

x=1

Explanation:

By looking at the equation we can see that the x intercept stays the same, so this is a vertical slope. in slope intercept form (y=mx+b) this looks like

x=b

and since we can see the two points x is always 1, we know that b is 1 so

x=1
