Answer:
1. the y intercept is supposed to be -1 not 1
2a. The slope is a positive slope, its supposed to be a negative one.
2b. Jake wrote a slope of 1/4 instead of -1/4
Explanation:
For the second part the point (12,4) is not on the graph.
Plug in the x and y values into the equation y = (-1/4)x - 1
So 12 = (-1/4)(4) - 1
12 = (-1) - 1
12 = -2
12 does not equal 2. Therefore, the point (12,4) does not lie on the graph above.
Hope this helps!
