I'm here to help. Those 3 points all lie on the same line. We know this because if we find the slope between any 2 of those points, it is the same. I'll show you: 
. Now another 2 points: 
. The same holds for the first and third points. So we got that out of the way. Now we will pick any one of those points and use the x and y values and our slope to write an equation of that line and then finally solve for the x and y intercepts. I'm going to use the first point (10, 20): 
. We will simplify to get it into y = mx + b form: 
and 
and finally, 
. The y-intercept exists when x = 0, so when x = 0, y = 36. The x-intercept exists when y = 0, so when y = 0, x = 22.5. In summary, y-intercept: (0, 36). x-intercept: (22.5, 0) and you're all done!
Answer:
12% increase
Step-by-step explanation:
Each year the sales increase by $50,000.
430,000 + 50,000 = 480,000
480,000 + 50,000 = 530,000
To find the percent change, write a proportion using 2 of the years.
To solve for x, cross multiply the numerator with the denominator of each fraction.
480,000(100) = 430,000(x)
48,000,000 = 430,000x
111.62 = x
Rounded this is 112% or 12% above 100%.
