Answer 1

13

Explanation:

Let the missing value be c.

y = -3x + c

Put x as 0, and y as 13.

13 = -3(0) + c

13 = 0 + c

13 = c

Answer 2

13

Explanation:

Since a point on the line is (0, 13) we know that the y-intercept is 13. The answer is already written in slope-intercept form so the answer is 13.
