Q. (a) Does (2,−2) satisfy the equation 23x+y−4=0 ?NoYes
Identify values of x and y: Identify the values of x and y in the point (2,−2). We have x=2 and y=−2.
Substitute values into equation: Substitute the values of x and y into the equation 23x+y−4=0. Substitute 2 for x and −2 for y into the equation. Calculation: 23⋅2+(−2)−4=0
Perform multiplication and addition: Perform the multiplication and addition to simplify the equation.Calculation: 3+(−2)−4=0
Combine numbers to check equation: Combine the numbers to see if the equation is satisfied.Calculation: 3−2−4=−3
Determine if equation is satisfied: Determine if the simplified equation equals zero.−3=0, so the point (2,−2) does not satisfy the equation 23x+y−4=0.
