Answer:
<h2>y = -x - 1</h2>
Step-by-step explanation:
From the graph we have:
y-intercept = -1
x-intercept = -1
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
m - slope
b - y-intercept
Therefore we have: <em>y = mx - 1</em>
Put the coordinates of the x-intercept to the equation:
(-1, 0) → x = -1 and y = 0:
0 = -1m - 1 <em>add m to both sides</em>
0 + m = -m + m - 1
m = -1
Finally we have the equation:
<em>y = -1x - 1</em>
AD = DC
y + 6 = 2y
y - 2y = -6
-y = -6
y = 6
DC = 2y = 2(6) = 12
answer
DC = 12
Answer:
15
Step-by-step explanation:
Opposite angles, angles that are opposite each other when two lines cross, are also known as vertical angles because the two angles share the same corner. Opposite angles are also congruent angles, meaning they are equal or have the same measurement.
Therefore 60 = x + 45 or 60 - 45 = x =15
