A line includes the points (4,1) and (8, 2). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.

y = 4x

Step-by-step explanation: Slope intercept form is y = mx + b where m is the slop and b is the x intercept

We can solve for slope using the given points

(2-1)/(8-4) = 1/4, thus m = 1/4

y = 1/4x +b

Now to solve for b, we can just plug in one of the points to see what makes b work

1 = 4*(1/4) + b

1 = 1 +b

b = 0
