Answer:
k = 2
Step-by-step explanation:
Slope Formula: ![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Step 1: Replace variables
![\frac{(k+3)-2}{3+1} =\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%28k%2B3%29-2%7D%7B3%2B1%7D%20%3D%5Cfrac%7B3%7D%7B4%7D)
Step 2: Combine like terms
![\frac{k+1}{4} =\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bk%2B1%7D%7B4%7D%20%3D%5Cfrac%7B3%7D%7B4%7D)
Step 3: Solve for <em>k</em>
k + 1 = 3
k = 2
