A line through the points $(2, -9)$ and $(j, 17)$ is parallel to the line $2x + 3y = 21$. What is the value of $j$?

2 x + 3y = 21 slope = - 2/3 parallel slope is the same = - 2/3

slope calculation (y1-y2) / (x1-x2) ( it does not matter which point you assign 1 or point 2)

(17- -9)/ (j-2) = - 2/3

j = -37
