Answer:
Step-by-step explanation:
The equation of the line in point-slope form is:
Where m is the slope and is a point of the line.
The slopes of two perpendicular lines are opposite reciprocal, then the other slope is:
m=
Substitute the slope and the given point into the equation, then you obtain:
9 - [42 - (3 + 2)]
Parentheses first:
9-[42-5]
Brackets next:
9- 37
Now subtract to get -28
2nd statement is false
A
By vertical line test, if you draw any vertical line, except for A, all graph meet at more than two points. So, graph A represents y as a function of x.
