sorry if that isnt right..
Answer:
B:-1
Step-by-step explanation:
Just took test 2021
Two correct answers:
9 + x
x + 9
Or you can say
x - -9
or
9 - -x
a) find the slope of the line using the given points.
Slope: 9 - -3/6-0 then slope is 12/6 which is 2
Then using formula: y = mx+b
-3 = 2(0) + b
b = -3
The equation is: y = 2x -3
B. Slope of a perpendicular is -reciprocal of first line. So here the slope will be -1/2
y = mx + b is used again
2 = -1/2(0) + b
b = 2
The equation is: y = -1/2x +2
