AB top side = 7x + 4 and BC right side = 3x + 20. What is DC diaganol?

Two different linear functions are shown below with two points given from each function. use slope-intercept form or point-slope form to find the equation of each. linear function a points: (–5, –2), (–5, 7) linear function b points: (7, –5), (–2, –5) function a has: the equation of line a is: function b has: the equation of line b is:

100 points, hi, i’m not sure how to get the equation from the graph and table.
