Answer

3x+4y=5 Explanation 1. Identify Linear Equation A linear equation is in the form ax + by = c, where a, b, and c are constants, and the variables are to the first power without absolute values or exponents greater than 1. 2. Analyze Each Option - 9\vert x-5\vert +y=2: Contains absolute value, not linear. - 3x+4y=5: Matches the linear form ax + by = c. - y=2\vert x-3\vert +7: Contains absolute value, not linear. - y=3x^{2}+6x+9: Contains x^2, not linear. - y=6(x-2)^{2}+10: Contains (x-2)^2, not linear.

Explanation

1. Identify Linear Equation<br /> A linear equation is in the form $ax + by = c$, where $a$, $b$, and $c$ are constants, and the variables are to the first power without absolute values or exponents greater than 1.<br /><br />2. Analyze Each Option<br /> - $9\vert x-5\vert +y=2$: Contains absolute value, not linear.<br /> - $3x+4y=5$: Matches the linear form $ax + by = c$.<br /> - $y=2\vert x-3\vert +7$: Contains absolute value, not linear.<br /> - $y=3x^{2}+6x+9$: Contains $x^2$, not linear.<br /> - $y=6(x-2)^{2}+10$: Contains $(x-2)^2$, not linear.
