Question

Y = mx + b -2 = 3(4) + b -2 = 12 + b -14 = b; the y-intercept is -14 What is wrong with this answer?

Answer 1

There is nothing wrong with the answer obtained

Explanation:

Given the equation :

Y = mx + b

-2 = 3(4) + b

-2 = 12 + b

-14 = b

The correct calculation :

Y = mx + b

-2 = 3(4) + b

-2 = 12 + b

Subtract 12 from both sides

-2 - 12 = 12 + b - 12

-14 = b

Based on the details of the question given, the intercept, b is - 14 ;

Hence, there is nothing wrong with the answer
