What are you trying to solve for?
y as a function of x?
x as a function of y?
Please be more specific.
Thanks!

This is a linear equation
-3x+4y-5=-14
Add 5 to each side to simplify
-3x+4y=-9
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation -3+x+%2B+4+y+=+-9 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+--3%2F4.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -9/-3 = 3.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -9/4 = -2.25.
  • Slope is --3/4 = 0.75.
  • Equation in slope-intercept form: y=0.75*x+-2.25.
