Answer:
The slope of a parallel line is 3
Explanation:
In a general way parallel lines share the same value of the slope, so all that we have to is to identify the slope.
We are given a line equation in slope-intercept form that is,

Here m which is the coefficient or number in front of x stands for the slope, while b stands for the y-intercept.
Identifying the slope.
For the given line equation y = 3x+5, we have for the coefficient or number in front of x as 3, so we have that the slope m is 3.
Then for parallel lines we know that slopes have the same value, so the slope of a line that is parallel to y = 3x+5 has slope m = 3.
