Question

Which equation represents a line that passes through(2,-1/2) with a slope of three

Answer 1

Answer:

y = 3x-13/2

Step-by-step explanation:

We have a slope and a point

The equation of a line is

y= mx+b where m is the slope and b is the y intercept

y = 3x +b

Substitute in x and y

-1/2 = 3(2) +b

-1/2 = 6+b

Subtract 6 from each side

-1/2 -6 = 6-6+b

-1/2 -12/2 =b

-13/2 =b

Putting this back into the original equation

y = 3x-13/2
