EXPLANATION
The given line JKL is a straight line. The angle on a straight line is 180 degrees.
This implies that the sum of the angles ![\begin{gathered} Solve for x in the equation above:[tex]\begin{gathered} x=180-30 \\ x=150\degree \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Solve%20for%20x%20in%20the%20equation%20above%3A%3C%2Fp%3E%5Btex%5D%5Cbegin%7Bgathered%7D%20x%3D180-30%20%5C%5C%20x%3D150%5Cdegree%20%5Cend%7Bgathered%7D)
That is the value of x.
Answer:
y=5x+31
Step-by-step explanation:
y=mx+b
