Question

Please help me answer this.

Answer 1

Answer:  B.   y=3x+7.5

Step-by-step explanation:

First, you find m by doing $\frac{y_2 - y_1}{x_2 - x_1} =m$ . You end up with $m=2$ . Then you plug it into $(y-y_0)=m(x-x_0)$ to find the b in $y=mx+b$ . When you do that, you get $b=7$ . So, you end up with the equation of the table as $y=2x+7$ and since it's a linear function, the slope (m) won't change. Now you compare this equation to the others given. The slope in answer A is too small and the y-intercepts in answers B and C are too small, so you are left with b as your only option.

Answer 2

Answer:

B. y=3x+7.5
