Q. y−3=2(x+1)Complete the missing value in the solution to the equation.(−1,□)
Substitute x-value: Substitute the given x-value into the equation to find the corresponding y-value.We are given the point (−1,□), which means x=−1. We need to substitute x=−1 into the equation y−3=2(x+1) to find the y-value.y−3=2(−1+1)
Simplify equation: Simplify the equation by performing the operations inside the parentheses.2(−1+1)=2(0)=0Now we have y−3=0
Solve for y: Solve for y by adding 3 to both sides of the equation.y−3+3=0+3y=3
Check solution: Check the solution by substituting the found y-value back into the original equation.Substitute y=3 and x=−1 into the equation y−3=2(x+1) to verify the solution.3−3=2(−1+1)0=2(0)0=0This confirms that y=3 is the correct solution for x=−1.
