what is the y-intercept of the line 8x - 5y = -10

Sagot :

We want to obtaint y=ax+b form, lets do this
8x-5y=-10      /-8x   (subtract 8x both sideS)
-5y=-8x-10      /:-5  divide both sides by -5
y=[tex] \frac{-8}{-5} x+2[/tex]
y=[tex] \frac{8}{5} x+2[/tex] - its the answer
8x-5y=-10
-+5y +5y
------------------
8x=-10+5y
+10 +10
----------------
8x+10=5y
÷5 ÷5
-----------
1.6x+2=y
or Y=8/5x+2
