Step 2. Find the value for b.

Since each value of y is moved 2 units for x, , or b² is required to move between two points. To determine the b -value, set up an equation and solve.

10â€¢b² = 250

b² = 25

b = 5

Step 3. Use an ordered pair to solve for the value of a.

For this example, use the point (1, 10)

Step 4. Use the values of a and b to write an equation.
