You can put this solution on YOUR website! a)We can just try inputing some numbers, (4,3) this works because  . (6,6) this works because  . Finally, (8,9) this works because  .
b) Now for graphing:
| Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc |
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. 6/3 = 2.
- Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 6/-2 = -3.
- Slope is -3/-2 = 1.5.
- Equation in slope-intercept form: y=1.5*x+-3.
