Lesson 2-1 practice
v 13. attend to precision. justify each step in the solution of 5x + 15 -
below by stating a property or providing an explanation for each
5x + 15 = 0
5x + 15 – 15 = 0 – 15
5x = -15
x = -3

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?

Evaluate the expression for the given value of the variable. ∣-4b-8∣+∣-1-b^2 ∣+2b^3 ; b=-2
