Answer:
Parallel lines
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 3 ← is in slope- intercept form
with slope m = 1
- x + y = 7 ( add x to both sides )
y = x + 7 ← in slope- intercept form
with slope m = 1
Parallel lines have equal slopes, thus the lines are parallel
Answer:
The axis of symetry is the X value that splits the graph in half. For this equation, the axis of symmetry is x= 
.
The vertex is the highest or lowest point on the graph. For this equation, the vertex is

Answer:
C
Step-by-step explanation:
Answer:
applying absolute law
if |u|=a, a>0 then u=a or u=-a
2x+5=15 or 2x+5=-15
2x=15-5 or 2x=-15-5
2x=10 or 2x=-20
x=5 or x= -10
It’s c because equal means well equal because of the sides
