You can put this solution on YOUR website! 10y+15x=20
Let x=0 and solve for y
10y+15(0)=20
10y+0=20
10y=20
10y/10=20/10
y=2 Plot (0,2)
:
Let x=2 and solve for y
10y+15(2)=20
10y+30=20
10y+30-30=20-30
10y=-10
10y/10=-10/10
y=-1 Plot (2,-1)
For lines you only need to plot two points unless otherwise specified. If you need to plot more, let x be even numbers to avoid fractions.
Connect the two points and you have a line that looks like:
