Answer:
z = 7 and z = 69
Step-by-step explanation:
In the given figure, two lines are cut each other.
Here we have to use the following property.
If the two lines intersect each other, then the opposite sides are equal.
Therefore, 11x + 34 = 111
Now we have to find the value of x.
Solve for x.
11x = 111 - 34
11x = 77
Dividing both sides by 11, we get
x = 77/11
<u> x = 7</u>
Now we have to find the value of z.
Adjacent angles add upto 180 in a straight line.
Therefore, 111 + z = 180
Subtract 111 on both sides, we get
111 + z -111 = 180 - 111
<u>z = 69</u>
Therefore, z = 7 and z = 69
Hope you will understand the concept.
Thank you.

Answer:
1)y=3x-2
2)y=x-4
Step-by-step explanation:
1)As we know slope intercept from
y=mx-b
y=3/1x-2
y=3x-2
2)y=mx-b
y=1x-4
y=x-4
