Explain what i need to do 20 points

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

What is the solution to the equation in the & show work i’m very

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
