Answer:
When a line is parallel to another line, they have the same slope. So far the equation would be, y=4x+b. To find the value of b, substitute the given point into the equation.
8=4(-1)+b
8=-4+b
b=12
So, the equation of the line is y=4x+12.

Answer:
m∠1 = 93.5°
Step-by-step explanation:
By theorem of intersecting chords inside a circle,
If two chords intersect inside a circle, angle formed between the chords measure half the sum of the measures of the intercepted arcs.
m∠1 = 
= 
= 93.5°
Therefore, measure of angle 1 is 93.5°.
Answer:
m∠z= 58.7
Step-by-step explanation:
Remember, all triangles sum up to 180 degrees.
So, the equation would be: 31.3+90+m∠z= 180.
Step 1- Add to simplify.
(31.3+90)+m∠z= 180
121.3+m∠z= 180
Step 2- Subtract to both sides.
121.3+m∠z= 180
-121.3 -121.3
m∠z= 58.7
