Answer:
y = 1.5x + 3.2009
Step-by-step explanation:
I plotted your points and drew a linear regression line.
Its equation is
y = 1.5x + 3.2009
The regression line ignores the fact that the points fall along a smooth curve.
A parabolic regression line fits the data much better.
The equation for that line is
y = - 0.1647x² + 4.1357x - 5.6946
It is the equation for a vertical parabola opening downward.
2x10-1 as the decimal place is 0.2
At x-intercept, y value = 0,
For t(x), x = 1 when y = 0, i.e. x-intercept = 1
for 3x - 2y + 6 = 0, when y = 0,
3x - 2(0) + 6 = 0
3x + 6 = 0
3x = -6
x = -6/3 = -2
i.e. x-intercept = -2
Therefore, t(x) has the highest x-intercept of 1.
Property being demonstrated here is corresponding angles.
Meaning 72 = x.
