A barrel contains some water. More water is being added at a steady rate. After 3 minutes, the barrel contains 6 gallons. After 5 minutes, the barrel contains 8 gallons. Assume this is a linear function. What is the slope and y-intercept of the function representing this situation?

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?

1) what is the measure of the exterior angle, ∠uvw ? 2) in triangle man, what is the measure of the exterior angle at n (in degrees)?

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
