Question

Which equation represents a line that passes through (2, –1/2) and has a slope of 3?

Answer 1

Hello,

y+1/2=3(x-2)
or y=3x-13/2

Answer 2

Answer:

Step-by-step explanation:

Let the equation of the line is y = mx + c

where m = slope = 3

and c = y-intercept

Now the equation of this line will become

y = 3x + c

Since this line passes through (2, $\frac{-1}{2}$)

so  $\frac{-1}{2}$ = 6 + c

c =  $\frac{-1}{2}$ - 6

  =  $\frac{-13}{2}$

So the line will be y = 3x + $\frac{13}{2}$
