Question

A line has a slope of -1/2 and a y-intercept of 3.

Which equations represent the line?

Choose all answers that are correct.

A. 2y = 6 + x


B. x + 2y = 6


C. y = -1/2x + 3


D. (y - 2) = -1/2( x - 2 )

Answer 1

One equation is: y = mx + b (slope-intercept formula)

m = slope = -1/2

b = y-intercept = 3


y = mx + b (replce m with -1/2 and 3 with b)

y = -1/2x + 3

The answer is C
