Answer:
x = 9
Step-by-step explanation:
when two lines intersect, it creates four angles. vertical angles are the angles that are opposite to each other. in the attached image, 1 & 3 are vertical angle pairs, and so are 2 & 4.
since vertical angles are always congruent, 3x - 8 is equal to 2x + 1
3x - 8 = 2x + 1
add 8 to each side
3x = 2x + 9
subtract 2x from each side
x = 9
check your answer:
3x - 8 = 2x + 1
3(9) - 8 = 2(9) + 1
27 - 8 = 18 + 1
19 = 19
Answer:
y=x+2
Step-by-step explanation:
Use equation M=
this will give you the slope of the line.
to get b which is the y intercept take the y intercept which is 2
Answer:
(5,3)
Step-by-step explanation:
Well to solve the following,
y = 8 - x
y = x - 2
Graphically.
We need to graph both equations,
Look at the image below ↓
By looking at the graph we can tell the intercept point is at (5,3).
<em>Thus,</em>
<em>the solution is (5,3).</em>
