A. 11
B. 1
C. -1
D. -13


I trys but cant get it can i please get help?

Answer 1

C. -1

Explanation:

Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:

y = mx + b

-7 = -3(2) + b

-7 = -6 + b

-1 = b

So, the y intercept is -1.

The correct answer is C. -1
