Write an equation with a y-intercept of -1 and a slope of 1/2

y = (1/2)x - 1

Step-by-step explanation:

Follow the formula, y = mx + b, in which:

y = y

m = slope = 1/2

x = x

b = y-intercept = -1

plug in the corresponding numbers to the corresponding variables:

y = mx + b --> y = (1/2)x + (-1) --> y = (1/2)x - 1

y = (1/2)x - 1 is your answer.
