Answer:
Given:
,
,
,
formed by two intersecting segments.
In the given figure;
Linear pair states that a pair adjacent angle formed when two lines intersect.
Then by definition of linear pairs,
and
forms a linear pair
Also,
and
forms a linear pair.
Linear pair postulates states that the two angle that forms a linear pair are supplementary(i,e add up to 180 degree).
Then by linear pair postulates;

and

Substitution property of equality states that if x =y then, x can be substituted in for y or vice -versa.
then by substitution property of equality:

Addition property of equality states that:
if x =y, then x + z = y+ z
By addition property of equality:
hence proved!
Answer:
y=-5.5x+-5
Step-by-step explanation:
<em>the slope is -5.5</em>
<em>the y-intercept is what the y-axis is when the x-axis is zero</em>
<em>therefore the y-intercept is -5</em>
hope this helps
have a nice day!!
Answer:
(-3;-2)
Step-by-step explanation:
By replacing you get:
5*7-2*11+3*(-1) = 35-22-3= 10
so the answer is 10.

When x=0, y=-8, so that is the y-intercept.
When x increases by 1, y decreases by 2, so the slope is -2.
The equation of the function is
.. y = -2x -8
