Question

What is the answer for this questions and explain why

Answer 1

Answer:

B

Step-by-step explanation:

Well you first know that your y-intercept is -2 (look on the graph) so you can automatically cancel out option A and D. Now this leaves us with B and C. The only thing that is different between the two answers is the slope. Slope = Δy/Δx (change in y divided by change in x) So from (0,-2) to the next point (4, -1) How far is the x and y? Well you go up one and to the right 4. the change in y is up one (+1) and the change in x is right 4 (+4).

You can also do this

\frac{-2-(-1)}{0-4} = \frac{-1}{-4} = 1/4\\

(y2-y1)/(x2-x1) (the numbers are subscripts)

hope that helped:)
