Answer: B. y = 3x - 5

Explanation:

First ,we know Option C will not be an option because of the y-intercept (the point at which the line intersects the y-axis) is -5. This is shown by the point (0, -5). Option C shows it as 1.

We will substitute a point into the given equations and see if the simplified version remains true.

✗ A ➜ y = -3x - 5

➜ -2 = -3(1) - 5

➜ -2 ≠ -8

✓ B ➜ y = 3x - 5

➜ -2 = 3(1) - 5

➜ -2 = -2

✗ D ➜ y = -x - 5

➜ -2 = -1 - 5

➜ -2 ≠ -6

Using this method of substitution, we can see the answer is B.
