242 cm because 418/ 3.8 = 110, 110 x 2.2 = 242 cm
The linear equation that best fits the data is: y = 10x + 15.
<h3>How to Write the Linear Equation of a Data?</h3>
First, find the slope/unit rate (m) and the y-intercept/starting value, then substitute the values into y = mx + b.
Using two points on the graph, (1, 25) and (2, 35), find the slope (m):
Slope (m) = (35 - 25)/(2 - 1)
Slope (m) = 10/1
Slope (m) = 10
Substitute (x, y) = (1, 25) and m = 10 into y = mx + b to find b
25 = 10(1) + b
25 - 10 = b
b = 15
Substitute m = 10 and b = 15 into y = mx + b
y = 10x + 15

The formula of a slope:
We have the points A(-6, 6) and B(12, 3). Substitute:
Therefore we have 
.
Put the coordinates of the point B to the equation:
<em>add 2 to both sides</em>

Answer:
3.5
Step-by-step explanation:
These are similar triangles.
BC:AC = BD:AD
6:5 is the ratio.
Then, simply multiply:
4.2 x 5/6 = 3.5
So, x = 3.5!
