Question

15. Which of the following is the equation of the graph below? (2 points) y - - 3 2 -10 1 2 3 4 5 (A) y = -2x + 4 (B) y = 2x + 4 (C) y = -x - 2 (D y = -2x - 2

Answer 1

`\begin{gathered} \text{ We see that the y-intercept is 4, } \\ \text{and the slope is} \\ m=(4-0)/(0-(-2)) \\ m=(4)/(2)=2 \\ \\ \text{Thus the equation is } \\ y=2x+4 \end{gathered}`
