Question

What is the slope of a line that runs parallel to y = 2 x + 5?

Answer 1

The equation "y=mx+b"  is the slope-intercept forme of a line with slope "m" and y-interceptept (0,b)

In this case:
y=2x+5;
the slope "m" will be equato to : "2".

Answer: the slope is 2.

Answer 2

Parallel lines have equal gradients;
So,
y=2x+5
The gradient is 2
The parallel line also has a gradient of 2
