Well we know that 1 inch is 2.54 cm. But how wide is .18? Lets do .18 x 2.54 to get 0.4572. Now lets add 2.54 + 0.4572 to get 2.9972. This means that the maximum width of the aorta is 2.9972 cm. Hope this helped :)
The slope-intercept form:

m - slope
b - y-intercept
We have the slope m = 4 → 
and point (1, 6). Substitute:

<em>subtract 4 from both sides</em>

<h3>Answer: y = 4x + 2</h3>
Answer:
