this is a econ 1530 question. please could i get a detailed solution

1. A linear function (y(x) = ar + b) is known to go through the points (1, 3) and (2, 2) where, as usual, the first element for each point is the 'r' value and the second element of each point is the 'y' value. A second linear function (t(x) = cr + d) is known to go through the point (1, 1) with slope equal to 2. i. Solve for y(r) = ar + b that goes through (1, 3) and (2, 2). ii. Solve for t(x) = cr + d that goes through (1, 1) with slope equal to 2. iii. Find the point where y(r) and t(x) intersect. iv. Provide a careful graph of y(), t(x) and their intersection point
