Find the equation of a line having a slope of -2 and y intercept of 1.

The equation of a line in slope-intercept form is given by:

y = mx + b

y = vertical variable   ( dependent variable )

m = Slope

x = Horizontal variable   ( Independent variable ) 

b = is the y-intercept, the point where the line crosses the y-axis.

Given :-  m = -2 , b = 1

y = -2x + 1

2x + y = 1
