Ernesto tried to determine the solution for the system of equations using substitution. His work is shown below. x – y = 7

3x – 2y = 8

Step 1: x = y + 7

Step 2: 3(y + 7) – 2y = 8

Step 3: 3y + 7 – 2y = 8

Step 4: y + 7 = 8

Step 5: y = 1

In which step did Ernesto make the first error?

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?
