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. -18/4 = -4.5.
- Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -18/-6 = 3.
- Slope is -4/-6 = 0.666666666666667.
- Equation in slope-intercept form: y=0.666666666666667*x+3.
