She started with 81 baseball cards.
So fill out the coordinate with those given numbers, and count how far apart they are and you will get your answer. Then times it by x.
Answer:
When you have a equation you can easily find the x value and y value which you can assume the x-intercept is (x,0). and y-intercept is (0,y)
Hope this helped.
Is there more to this question?
Answer:
the y intercept is 4
and frm that point to another spot on the line you go DOWN one unit (negative)
and two units to positive (to the right) thus the slope is - 1 (down) and 2 positive to the right
-1/2 = slope
y = -1/2 + 4
