Answer:
<h2>3x - y + 7 = 0</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
Put the given y-intercept b = 7 and the coordinates of the point (-2, 1) to the equation:
<em>subtract 7 from both sides</em>
<em>divide both sides by (-2)</em>

We have the equation:

Convert it to the general form
:
<em>subtract 3x and 7 from both sides</em>
<em>change the signs</em>

Answer:
Step-by-step explanation:
Angles EBC and EDC are the same. and straight lines equal 180
so now to solve for x

Answer:
I think its 86
Step-by-step explanation:
As the two lines going in the same direction are parallel and angles within parallel lines add to 180.
so 180-94=86
