Step-by-step explanation:
<u>Linear Modeling</u>
It consist is setting up a linear relationship between two variables, given some experimental data. Only 2 points are needed to set up the equation of a line, but if more than 2 points are used, then the result should use statistical approaches like linear regression to find the best-fit line.
For the question at hand, Marty practices his piano lessons 11 minutes the week #1. It provides the first point (1,11). He practices 25 minutes per day on the third week. It gives us another point (3,25). This is enough to find the equation of a line. The general formula for a line, having two points (m1,w1) (m2,w2) is

Let's plug in our values

Simplifying:


Answer:
X intercept = (2,0)
Y intercept = (0,-3)
Step-by-step explanation:
To find x intercept make y into 0
3(x) - 2(0) =6
3x = 6
x = 2
X intercept = (2,0)
Y intercept do the same
Y intercept make x into 0
3(0) - 2(y) =6
-2y = 6
y = -3
Y intercept = (0,-3)
You would have to multiply 3.14x29.8 which is 93.572, or 93.6 to the nearest tenth
