F(x) = -9x + 4
y = -9x + 4
x = -9y + 4
x + 4 = -9y
-x/9 - 4/9 = y

h(x) = -4/5x + 1 3/5
y = -4/5x + 1 3/5
x = -4/5y + 1 3/5
x - 1 3/5 = -4/5y
-1 1/4x + 2 = y

Mathematics

15 units

Step-by-step explanation:

Given

The endpoints of the line segment are $(-7,10)\ \text{and}\ (-6,-5)$

The length of the line segment is given by the distance formula i.e.

$d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}$

Insert the values,

$\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}$

Therefore, the length of line segment TU is 15 units
