(8, -2) and (4, -4) are on the line. what is slope-intercept

Y=1/2x-6

Step-by-step explanation:

(8,-2) (4,-4)

To find the slope: m=y2-y1

x2-x1

-4+2 -2 1

M= = ___ = __

4-8 -4 2

Point slope formula: y-y1=m(x-x1)

y+2=1/2(x-8)

y= 1/2x-6

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

the second option
