That means we can elimate two answer choices, which 2 can we eliminate?

Also, you could look for the slope using the points (0, 6) and (9, 0)

how so? that confuses me luigi

Since it's already in slope intercept form, just look for the m.

  • anonymous
so its either a or c

\(\sf\Large Slope=\frac{y_2-y_1}{x_2-x_1}\)

oh so just look at the points

i get it now

thank you guys for your help!

Plug in x=0 into a or c and see if it gives you the correct y-intercept that is shown in the graph :)

c?
