Question

5x+5y=25 is this linear

Answer 1

`\text{First, simplify the equation:}\\\\5x+5y=25\\\\\text{Subtract 5x from both sides}\\\\5y=-5x+25\\\\\text{Divide both sides by 5}\\\\y=-x+5\\\\\text{The slope of the line is -1, so this is a linear equation, due to the fact}\\\text{that the slope is at a constant`

Answer 2

No,it's not linear because it doesn't have Y=2x+1.
