Step 1: Find the slope:
     
This gives you  , but we need to find b.
, but we need to find b.
To find b, substitute in one (x,y) pair and it doesn't matter which one.  I'll go with (4,-2):
     ![\begin{aligned}-2&=-\dfrac{3}{2}(4)+b\\[0.5em]-2&=-6+b\\[0.5em]4&=b\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D-2%26%3D-%5Cdfrac%7B3%7D%7B2%7D%284%29%2Bb%5C%5C%5B0.5em%5D-2%26%3D-6%2Bb%5C%5C%5B0.5em%5D4%26%3Db%5Cend%7Baligned%7D)
Now take that b-value and plug in into the slope-intercept form:
      
It's always a good idea to toss in the other x-value from the other point, to make sure it checks out.

Answer:
12.5
Step-by-step explanation:
Step 1:
0.4 ( 3b + 10 ) = 19     Equation
Step 2:
1.2b + 4 = 19       Multiply
Step 3:
1.2b = 15    Subtract 4 on both sides
Step 4:
15 ÷ 1.2    Divide
Answer:
b = 12.5
Hope This Helps :)
