The equation is already in standard form, so we will just use the solver to illustrate it.

Standard form is ax+by=c

-2x%2B5y=15

I hope this helps!

Equation -2+x+%2B+5+y+=+15 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+--2%2F5.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 15/-2 = -7.5.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 15/5 = 3.
  • Slope is --2/5 = 0.4.
  • Equation in slope-intercept form: y=0.4*x+3.
