Answer:
gradient = - 2 , y- intercept = 1
Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
given
2x + y = 1 ( subtract 2x from both sides )
y = - 2x + 1 ← in slope- intercept form
with gradient m = - 2 and y- intercept c = 1
