Question

"Which of the following equations has a graph, which is parallel to the graph of y=1/2x+3"
A)y=1/2x+5
B)y=-2x+5
c)y=2x+5
d)y=-1/2x+5

Answer 1

The slope of a parallel line is the same or different of the slope of a given line?

Answer 2

They have the same slope. Thus, A

Answer 3

Equation of a line in slope intercept form
\[y=mx+c\]
m=slope
c=y intercept
here \[y=\frac{1}{2} x+c\]

Answer 4

Here slope of the given line is
\[m=\frac{1}{2}\]
Two lines are parallel if they have the same slope
