The y-intercept is being changed. In the equations given we are using the formula (y=mx +b), b means the y intercept. In this we are changing the y intercept from 2 to -1. There is nothing else being changed.
Y=-3 on the graph question
Equation for the parallel line through (9,-11) is y=-2/3x-5
The slope intercept form of -8x=2-2y is y=4x+1
The equation of a perpendicular line through (15,8) is y=-7/5x+29 :)
Answer:
≈ 56°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin ? = 
= 
, then
? = 
( ) ≈ 56° ( to the nearest degree )
