What is the equation if the relationship

Answer:
y = 0.85x +3.5
Step-by-step explanation:
The table entry for x=0 tells you the y-intercept is 3.5.
Each of the y-values changes by 85 when the x-value changes by 100, so the slope is ...
Δy/Δx = 85/100 = 0.85
Now we have enough information to write the equation in slope-intercept form:
y = mx + b . . . . . where m is the slope and b is the y-intercept
y = 0.85x + 3.5
