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. -1/-1 = 1.
- Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -1/2 = -0.5.
- Slope is --1/2 = 0.5.
- Equation in slope-intercept form: y=0.5*x+-0.5.
