-7

-1

✓ Correct

Detailed Explanation

Choice C is the best answer. Slope = 4. y - 7 = 4(x - 2). y = 4x - 1

Why others are wrong:

A: 7 is incorrect because it does not satisfy the equation.

B: -7 is incorrect because it does not satisfy the equation.

D: 1 is incorrect because it does not satisfy the equation.
