Final answer:
To find k for the point (-1,k) to satisfy the equation y=-5x+3, substitute x with -1, yielding k equals 8.
Step-by-step explanation:
The question asks to determine the value of k so that the point (-1,k) satisfies the equation y=-5x+3. To find the value of k, we'll substitute x=-1 into the equation and solve for y, which represents k in this case.
Starting with y = -5x + 3, we substitute x = -1: y = -5(-1) + 3 = 5 + 3 = 8. Therefore, k must be 8 to make the point (-1,k) a solution to the equation.
The correct answer is D. Ok=8.
