You can put this solution on YOUR website!
y=4/3x+7
3y=4x+21
-4x+3y=21
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation -4+x+%2B+3+y+=+21 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+--4%2F3.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 21/-4 = -5.25.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 21/3 = 7.
  • Slope is --4/3 = 1.33333333333333.
  • Equation in slope-intercept form: y=1.33333333333333*x+7.
