Question

What is the slope-intercept equation for the line below? (0,1) (4,3)

Answer 1

y2 - y1

---------

x2 - x1

3 - 1        2            1

------- = -------- = --------

4 - 0        4            2

Find the y-intercept:

1 = 1/2(0) + b

1 = 0 + b

-0  -0

1 = b

The slope-intercept equation is:

y = 1/2x + 1

so its D
