Question

Write the equation of the line that passes through the given point and has the given slope:

(-9, 0) and m = -1


​

Answer 1

Answer: y + x + 9 = 0

Explanation:

equation of a line with the following values is

y - y1

------- = -1

x - x1

enter the values of the coordinate x1 and y1 into the formula above

y - 0

------- = -1

x - (-9)

y - 0

------- = -1

x + 9

now cross multiply to have it in a linear form

y - 0 = -1( x + 9 )

y - 0 = -x - 9

y + x = -9

y + x + 9 =0

Answer 2

y=-x-9

Explanation:

y-y1=m(x-x1)

y-0=-1(x-(-9))

y=-1(x+9)

y=-x-9
