Do you have a picture where I can understand it much better?
100 / 60 = 1.66666667 , 1.66666667 x 39 = 65
The correct answer is A) y - 4 = -2/5(x + 1)
We know this because of the basic form of point slope form, which is shown below.
y - y1 = m(x - x1)
In which the point (x1, y1) is on the graph and m is the slope. When counting the slope, we can see that it is -2/5 based on the fact that for every two spaces the graph travels down, it moves to the right five. This eliminates options C and D and gives us this form to work with.
y - y1 = -2/5(x - x1)
Now we have the point (-1, 4), so we can plug this in to match it with a formula.
y - 4 = -2/5(x - -1)
y - 4 = -2/5(x + 1)
