Question

Find the equation of the line that has a slope of -½ and passes through the point (-6,9)

Answer 1

y = -1/2x +6

Explanation:

We can use the slope intercept form of a line

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

y = -1/2x +b

Substitute the point into the equation

9 = -1/2 (-6) +b

9 = 3+b

9-3 =b

6 =b

y = -1/2x +6
