Answer:
Step-by-step explanation:
Allow me to rewrite your question and hope it will fit the original one: 
<em>Jackson recorded the growth of a plant over 10 weeks. The equation </em><em>y=0.25x+4</em><em> represents the height y in inches over time x in weeks what does the y intercept represent In terms of the situation</em>
My answer: 
As we know that y intercept is the value of y at the point where the line crosses the y axis (the value of x =0) 
So in this situation, if x= 0, it means the height of the tree (y-intercept) initially be at 4 at week 0. 
Hope it will find you well.
