I need help on this one.
Flura [38]

Answer:

1) 180 is a straight line, so 180 - 118 = <em>62</em>

2) 180 degrees are in a triangle, so 180 - (62) - 73 = <em>45</em>

3) 180 is a straight line, so 180 - 73 = 107. There are 180 degrees in a triangle, so 180 - 49 - 45 = <em>86</em>

A line includes the points (9,0) and (-9,2). What is its equation in slope-intercept form?
horsena [70]
Y=mx+b

First use the two point slope formula to find m

(y2-y1)/(x2-x1)
(2-0)/(-9-9)
2/-18
1/-9=m

Next use the point slope formula to find the answer

y-y1=m(x-x1)

y-0=1/-9(x-9)

Now use Distributive Property 
y-0=1/-9(x)+1/-9(-9)
y-0=1/-9x+1

Your answer would be 
y=-1/9x+1
