On the bottom left, the answer is subtraction property of equality because you need to subtract 4x to the 7x to simplify the equation.
The answer to this question would be B, -3. The reason for this is because when you have an equation in slope intercept form, it would be y = mx + b. In this case your b is equal to 0 so you have only y = mx. The variable m represents the slope, which is in this case, equal to -3. Hope this helps.
