Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .- X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -9/-3 = 3.
- Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -9/-3 = 3.
- Slope is --3/-3 = -1.
- Equation in slope-intercept form: y=-1*x+3.
