Answer:

y =
(3)/(2)x +
(5)/(2)

✓ I believe you did do your work correctly

Explanation:

[] First, we will find the slope.

-> M =
(y_(2)-y_(1) )/(x_(2)-x_(1)) or M =
(y_(1)-y_(2) )/(x_(1)-x_(2))

-> M =
( 1-4)/(-1-1)=(-3)/(-2)=(3)/(2)

[✓] Good job, you appear to have done the slope correctly

[] Next, we will solve for the y-intercept

-> This can be found by taking what we have so far of our equation, plugging a point in, and solving for b

-> y =
(3)/(2)x + b

-> 4 =
(3)/(2)(1) + b

-> 4 =
(3)/(2) + b

->
(5)/(2) = b

[✓] Fantastic, it appears you have correctly found the y-intercept as well

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
