Q. y=−2x+4Complete the missing value in the solution to the equation.(□,−2)
Substitute y-coordinate: Substitute the given y-coordinate into the equation to find the corresponding x-coordinate.We have y=−2x+4 and we are given that y=−2. So, we substitute −2 for y in the equation to get −2=−2x+4.
Solve for x: Solve the equation −2=−2x+4 for x. We can do this by first subtracting 4 from both sides of the equation to isolate the term with x on one side. This gives us −2−4=−2x+4−4, which simplifies to −6=−2x.
Divide to find x: Divide both sides of the equation −6=−2x by −2 to solve for x. This gives us (−6)/(−2)=(−2x)/(−2), which simplifies to 3=x.
