Question

Which equation represents a line that passes through (–9, –3) and has a slope of –6?

y – 9 = –6(x – 3)
y + 9 = –6(x + 3)
y – 3 = –6(x – 9)
y + 3 = –6(x + 9)

Answer 1

y+3= -6(x+9)

Explanation:

Slope is represented as M

Name the numbers in bracket as y1 and x1

You have to use the formula which is:y-y1=m(x-x1)

Then you substitute the numbers into the formula

y--3=-6(x--9)

when two negatives meet the turn to positive

thats how we can conclude that the answer is y+3=-6(x+9)
