Step-by-step explanation:
the answer is in the above image
The y-intercept is the "b" in the slope-intercept form of y=mx+b. Based on the equation you wrote, you can substitute each of your known values into the slope-intercept form.
set up the ratios:
3/5 = x/15
Cross multiply:
45 = 5x
Divide both sides by 5:
X = 9
The model would be 9 inches long
