Question

Write the equation of a line in SLOPE INTERCEPT FORM with the following information.

m=1/2 and it goes through (3, 1).

Answer 1

y=1/2x+b
1=1/2(3)+b
b= -1/2

Answer is y=1/2x -1/2

Answer 2

y = 1/2x-1/2

Explanation:

y = mx+b is the slope intercept form of a line

where m is the slope and b is the y intercept

y = 1/2x +b

We can substitute the point (3,1) in for x and y

1 = 1/2(3) +b

2/2 = 3/2 +b

2/2 -3/2 = b

-1/2 =b

y = 1/2x-1/2
