Carter graphs these equations and finds that the lines intersect at a single
point, (1, -1).
Equation A: 2x - 3y = 5
Equation B: 4x + 5y = -1
Which statement is true about the values x = 1 and y = -1?

Slope measures the rate of change in the dependent variable as the independent variable changes. (B) is the slope of the line. Slope means that a unit change in x, the independent variable will result in a change in (y) by the amount of (B). slope = change in (y) change in (x)rise run. Slope shows both steepness and direction.
