Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
y = mx + b
m - slope
b - y-intercept
We have the equation:
y = 2x - 1 → m = 2, b = -1
The slope of this equation is 2.
In a y=mx+b equation, the slope is 'm,' so whatever number is before x in an equation like this is the slope.
So y=mx+b -> y=2x+b -> 2=m, b=-1
