5) Which strategy or strategies would you use for the first step be to simplify this problem? 3(x+4)=15 (can choose more than one if needed) 1, Add x + 4 to get 3 + 4x = 12
2, Distribute the 3 to make 3x + 4 = 15
3, Divide by 3 to get x + 4 = 5
4, Distribute the 3 to make 3x + 12 = 15​

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?
