Find the value of athat makes the ordered pair a solution of the equation.

y=2x+5;-1,a

Short Answer

Expert verified

The value a=3 would make the ordered pair -1,a a solution of the given equation.

Step by step solution

01

Step 1. Given Information.

An equation: y=2x+5 and the point: -1,a

02

Step 2. Calculation.

To find the value of a, we will substitute coordinates of given point in our given equation and solve for a as:

y=2x+5(Givenequation)a=2(鈭�1)+5Substitutingx=鈭�1andy=aa=鈭�2+5a=3

Therefore, the value of a would be 3.

03

Step 3. Conclusion.

The value of a would be 3.
