Answer:

<h2>14. y = 6x - 5</h2><h2>15. y = -4x - 24</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercet → (0, b)</em>

The formula of a slope:

m=\sdeac{y_2-y_1}{x_2-x_1}

====================================================

14.

(2, 7), (0, -5) → <em>b = -5</em>

Calculate the slope:

m=\dfrac{-5-7}{0-2}=\dfrac{-12}{-2}=6

The equation of a line:

y=6x-5

15.

(-6, 0), (0, -24) → <em>b = -24</em>

Calculate the slope:

m=\dfrac{-24-0}{0-(-6)}=\dfrac{-24}{6}=-4

The equation of a line:

y=-4x-24

To show that triangle TRK= triangle TUK by the SAS postulate, what additional information is necessary?
Ivan
From the figure, we already have
RT = UT
and
TK = TK

Since these are already conditions for two sides being congruent, we only need an included angle to be congruent. So, the missing information is 
∠RTK <span>≅ </span>∠<span>UTK</span><span />
