Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation 1+x+%2B+7+y+=+7 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+-1%2F7.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 7/1 = 7.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 7/7 = 1.
  • Slope is -1/7 = -0.142857142857143.
  • Equation in slope-intercept form: y=-0.142857142857143*x+1.
