Given the equation:
y = 3x - 7
Using the slope intercept form:
y = mx + b
Where m is the slope
Here, the slope is 3.
Also, the slope of parallel lines are the same, this is because the parallel lines never intersect.
Two lines are parallel if they have the same slope.
Therefore, the slope of a line that is parallel to the line y = 3x - 7 is 3
ANSWER:
3
