Answer: 3rd quadrant
Solution:
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation 1+x+%2B+3+y+=+15 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+-1%2F3.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 15/1 = 15.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 15/3 = 5.
  • Slope is -1/3 = -0.333333333333333.
  • Equation in slope-intercept form: y=-0.333333333333333*x+5.
